I played around with these today at the shop and needless to say, I'm pretty darn impressed. They are a reward opening head like the Rage and Snypers but are built like a TANK. I like the G-5 toughness with them. No rubber bands to them and they claim that it only takes 3lbs of energy to open them. Pretty nifty I think. They do open completely on impact too, (I tested that ). I also don't think you have as high of chance at getting some "deflection" withthese heads. Looking for some feedback from you guys, likes, dislikes. I picked up a pack to try, we'll see if I can whack a nanny with one tommorow.
