Combat bats - any feedback?

[Hollow Grind]

DD has just about outgrown her Xeno, which has produced consistently for two years.

While waiting for the 2014 model to be released, I want to consider other bats and am trying to get her to swing as many different ones as she can. She didn't care for her teammates' CF5s (-11, -10, Insane,) and the Easton black/yellow 2-piece felt heavy compared to other 31/21 bats.

Anybody out there swinging Combats? I can't find much info online and would love to hear any feedback, good or bad, on this brand.
