IRL, I'll carry 4 or 5 wedges myself, depending on the course. I also carry my 3 hybrid and remove the 3 and 4 iron.
Sad to say, the irons are sets here on WGT, and until they choose to allow us to break said set, we're stuck with only 3 wedges... as long as we're willing to lose the hybrid.
Since I've been active in the forums (late June of this year), this topic has been brought up 4 times to my knowledge. I'm sure it's been hashed to death prior to that time. As they say, great minds think alike!
