Nothing wrong with wanting those sticks. I'm pretty good friends with the owner of the GOLFUSA here in Asheville and he says they're the best looking irons on the market. I hope to get mine soon dude. I'm not an S300 fan but they do work well. Start saving some $$$$ bro.
Similar size, topline, offset, etc. But mostly b/c the stock CFS shaft in the i20 is a 109gram shaft, and I want PXi 5.5's in my 588's, which are 108grams. Perfect preparation dude. Plus I just really wanted the 20's. Loved them the first time I hit them.
