Hey diatta I have a quick question. Are the alu pillow balls better to use than the steel ones or are they more of a hassle. Also what is the best way to tell if the alu pillow balls are bent. I got hacked a couple of times in Chaplin and traction rolled but I don't see any visual signs of damage on the pillow balls. I wish xray would just make ti pillow balls that's what I have on my m3 evo they are lighter and stronger than the steel ones that they replaced.
