| March 26, 2004 STONEMAN Men's 50 535 posts | SAFEST BALLS TO HIT. I put this up almost a yr. ago. If, one goes to: http://slowpitch.portal.dk3.com/article.php?sid=19 Experts Warn that Lower COR and Compression Softballs Won't Solve Safety Issue..... The 44 cor ball w/ a 375 comp.. Tom Decker, president of TRUMP Softballs „In reality, it‚s not safer,‰ he said. „ In the first 60 to 70 feet from the point of ball-bat impact, the travel distance is not going to change.‰...... „If safety is the objective, associations should require a more elastic or rubbery .50 or .47 COR ball with lower (375) Compression,‰ said Trump‚s Schullstrom. „That‚s because the lower the COR the less elastic - the harder - the ball.‰ ..........Using the new, more realistic techniques, a .40 COR ball came off the bat 3.57 miles per hour faster and went 11-12 feet farther than a .47 COR ball. ...... A recent set of tests by a major ball manufacturer that found ball compression differed markedly on each of the ball‚s four sides. That means that a ball may meet the compression standard on one or two sides, but be too hard on the other two sides MY POINT. The softball GODs have been told by the 3 major ball makers that the 47 or 50 cor ball w/ a 375 comp r the only safe balls that should be used. Why, r we seniors not hitting these balls. Why won't ASA, U-TRIP, NSA, SPA, ETC. listen? |
| March 26, 2004 TexasTransplant Men's 70 516 posts | I would think that distance would be greatly reduced on those four-sided balls, since you wouldn't get much roll. Lighten up, everybody! Let's enjoy this season. |
| March 26, 2004 Fred 45 posts | Here is something from an advertiser on this site, www.softballhitting.com. it is a litle long but seems to say something similar to what you have posted. "Ok. I will try here to simplify a complex issue. We all know about the hype surrounding bats, but what if any surrounding balls? It's probably more confusion rather than hype, but it should not be so. First whats more important Ball core or compression? Answer: compression. COR is simply the rate at which a ball will reflect back after being cast against an immovable object. So the higher the core the higher the reflectivity or the higher the bounce if you will. Core 47 has a higher bounce than a core 40. But core is not as important as compression, although if you could choose a core 47 with low compression this would be a good ball for a stock techzilla to hit for example. Unfortunately low comp balls usually are paired up with 40 cor. This is why it is important to separate the two. The compression is much more important and it's as simple as this : 375lb. comp balls are softer or "compress" more than 525 lb. balls. It takes 525lbs. of pressure per sq.inch to compress a 525lb. ball 1/4". It takes only 375lbs. of pressure to compress a 375lb. ball 1/4". So the higher the comp the harder the ball and the harder the ball the farther it will fly WITH THE RIGHT BAT. What is the right bat? Well lets look at a bit more. If you could choose and I know many times you can't unless it's your own practice, but if you could the ultimate ball for lets say an ultra would be high comp 525lb.ball with 40 COR as opposed to 47 COR. Most times though 525's are paired up with 47 COR. Now on a stiffer bat like the stock techzilla the best ball match would be 47cor and low 375 compression. Again you don't see this ball too often because usually low COR is matched with low comp., but there you have it." Fred 58 years young. |
| March 26, 2004 Bat-Heater Men's 50 64 posts | WOW! Very informative. |
| April 4, 2004 STONEMAN Men's 50 535 posts | FRED: Again, it seems that u did not understand the full impact. Did u read the article in full? Balls r being tested @ the speed of 60 MPH. New test w/ balls need to be done @ 100 & 120 MPH. If, players r swinging bats @ 100 to 120 MPH, then the TESTING LABS, need to test balls @ higher speeds. If, a bat is swung @ 100 MPH, the 1.20 BPF equals....a ball is coming off a bat @ 120 MPH. If, a bat is swung @ 120 MPH, the 1.20 BPF equals....a ball is coming off a bat @ 144 MPH. A ball hit @ 100 MPH is traveling @ 146.7'/sec. A ball hit @ 110 MPH is traveling @ 161.3'/sec. A ball hit @ 120 MPH is traveling @ 176'/sec. This means that pitchers have roughly 1/3 of a second or less to react. „It may be that the actual COR of the ball at real impact speeds (100 mph) may be very different from the balls stated COR,‰ they wrote. „The COR tests use an impact speed of 60 mph . . . and it has been shown that COR is a strong function of impact speed.‰................ A recent report showed that lower COR balls actually came off the bat faster than higher COR balls. The report, „The Effect of Softball Compression and Coefficient of Restitution on Batted Ball Speed,‰ was based on a new study technique that used actual bat speeds and new high-tech bats. Using the new, more realistic techniques, a .40 COR ball came off the bat 3.57 miles per hour faster and went 11-12 feet farther than a .47 COR ball.„The bottom line is that associations are trading the .47 COR for a more dense .44 COR, exactly the opposite of what they should be doing,‰ said Schullstrom. What is "COR", anyway? It is an acronym for Coefficient of Restitution, which is a uniform rating of the "liveliness" of any given softball. COR has a much greater effect on batted ball speed than does compression. So, if you're after maximum hit distance (from higher batted ball speed), look for the highest COR numbers. For example, a .47 COR will travel farther than a .44 COR yet both balls might meet the 525 lb standard. |
| April 7, 2004 DoubleL10 Men's 70 907 posts | Stoneman- I agree that the 60 MPH Batted Ball speeds currently being tested may not be realistic. I see you are proposing that bats be tested at 100 or 120 miles per hour. I assume we are talking about the same thing? If so, as I recall, Ray DeMarini indicated in his studies that it is uncommon for players - even Major open players - to have bat speeds even in the 90's. If that is the case, I would expect it to be very rare occurance in the senior class. I can only think of a couple of people who MAY swing the bat in the 90's or higher. I think the abilities of the class of player being regulated need to have some consideration in this dialogue. I certainly do not think standards should be set for the extreme minority of players. I would also expect that as we move down from Major to AAA to AA, the corresponding average BBS of the players would decrease. Just my $.02 worth. |
| April 7, 2004 crusher Men's 75 524 posts | DoubleL10, I agree with you. If batspeed is tested at 100+ there are very few who can to that. I can ocasionally get one out of the park. Here is a point, my 'measured' golf club head speed ranges between 104 and 109 mph. I know my bat speed is no where near that. Good post. |
| April 8, 2004 Fred 45 posts | Stoneman: The information I posted was taken directly from www.softballhitting.com. These are not my words. I was just trying to shed a little more light on the subject. You really need to have a degree in physics to understand all this. I personally don't care what kind of ball is used.
