This 17 wedges in a bag business is making us learn a whole new vocabulary. I've seen ads for some who call it a gap wedge, which makes sense to me. Others call it an approach wedge or attack wedge...
All that matters is that you figure out how far you hit it consistantly and use it with a smile on your face.
When I first posted in this thread, I was using the TaylorMade rac-OS irons. I've since had a pretty unreal experience, having hit an inexpensive model Taylor iron, the R540XD set. They are a store line club, but they actually feel better to me than the rac set and I bought myself some. They have a different trajectory and I'm longer with them. It's just plain weird. The rac set was ebay'ed and I can't wait to get out after work one evening. If we could get rid of this bad weather in South Florida, I'd be playing right now.
