Has anyone tried the Combat Maxum senior bat? It is very hard to find any information on this bat (other than manufactures specs) and it seems like it was in very limited production and supply.

Yes, I have a 28oz. Took a while to break it in, but it is pretty
hot right now. Hits as well as the black Centanarian. Has nice colors on it, with good size sweet spot.

Softball Fans has them on sale now for $69.

We hit both the 1 piece and 2 piece demos at Woodlawn a few weeks ago and they were pretty good performers. I'm not sure how many swings were on them before we were swinging them but the ball speed and distance surprised a couple of guys. It's a good buy for $69, just be patient until it breaks in.
Hope this helps.

Which one did you hit? The one piece or the black 2 piece?

I have the 2016 white Maxum and used it all of last year, it seemed to take forever to break in but the ball jumped through the infield and on line drives but it did not seem to carry well, that being said however, I have been using that bat hitting off of a tee all winter and probably have close to 3000 swings and it has not even cracked the paint. In a reverse item, I had a team mate swinging the same bat last year and half way through the season, his paint looked like he had taken a hammer to the bat as it was badly chipped. we both started using our bats at the same time...
