My daughter does a lot of tee work and hits machine some in the winter. I got tired of watching her use a $300+ bat for tee work (never let her use it for machine balls) so I bought her an old Techzilla off ebay. Her composites are CFX and CF8, both balanced, but the Techzilla is a bit endloaded. She loves hitting that Techzilla and never once bitched about having to hit it instead of her composites. We were playing an indoor tournament last weekend and used a restricted flight ball. She used her zilla and the ball seemed to jump better than did the composites.
