After demoing the Callaway X18s, Taylormade OSS, and Nike Slingshots I fell in love with the Cleveland CG4s. I likes the x18s second best but appreciated the feel of the CG4s. The Taylormades had a terrible grip IMO and if I bought those I would have to regrip immediately since they felt very very slick. The Nike Slingshots just made a strange whistling sound when you sung them, I am guessing the partially closed cavity back is the culprit and I found myself paying more attention to the whistle rather than my swing tempo. The CG4s just have a buttery smooth feel and are very forgiving, their CMM technology is for real. Also I liked that the CG4s for their size, they are not as oversized as some of the others yet offer as much forgiveness IMO. If you want some game-improvement irons these are a very very nice set of irons.
