The wacems are really new.. and just came out last year. I got 3 of them... and they are an amazingly tough head. Not to mention they hit right w/ my field points... and I was shooting them at 308fps. I also had good luck w/ the Magnus Stingers, Montecs, SteelForce... I haven't had a chance to try the slick tricks yet though.. but all the reviews on the forums speak nothing but high praises. I don't think you can go wrong w/ either head.
