They are all HOT. They are all pretty fragile also. I have broken one in each and every tourney I have played in. I have also broken one in HR Derby.
My current gamer Senior bat is 28 Balanced Reebok. (I also have 28 EL Reebok that is even hotter, but I like the balanced better)
I have owned, swung: Geezer, Grey Combat, Yellow Combat, Ambush, ASA Stamped Ultra II in 28 and 30, No Stamp Ultra II in 28 and 30, Senior Stamped Ultra II in 28, Demarini Senior One (blue), Reebok Melee Balanced and EndLoaded.
Looks like you like combat, the Grey combat was very good and the Ambush was also, I would recommend getting an Endloaded version of one of those. I just did not like the softer barrel. Overall, I think the combats are more durable. SBF has the centenarian for pretty cheap. I have seen a couple of those in action and they are no slouch also......
