I tried an APEX. I have heard it called a rebranded Rage X. I don't know about that- but it's pretty similar. The groove favors a bencher that touches low and tucked and quickly brings the weight back over his face to lock out. Overall, I seems like a solid well-made shirt that will probably work weel for someone that has mastered the new-school hard poly shirts like Rage X and Katana.
I am eager to try an ACE. I heard it is very similar in groove to Super Phenom- i.e. works well for benchers that touch high and push the weight straight up. However, given the issues with getting Metal gear altered, I have held off. I have not owned a single shirt that performed right out the UPS box. In fact, it took two rounds of altertions to get my Super Phenom where I want it.
