I don't know about the sole 100%. I go back and forth on it.
On one had, it's really good from the rough. I also think that the long and mid irons really work well with the thinner sole. I struggled with my 6 and 7 iron more than any other clubs in the Redline set, but that just isn't the case with the V2's.
On the other hand, I do see what I think are some negative effects with the PW. I could use a little more slide and little less dig some days. Keep in mind that this is coming from somebody who'd primary miss is slightly behind the ball.
This is the reason why I do not like using the PW around the green. There is very little bounce in it from what I have seen, and tends to dig straight in, rather than slide on the turf and scoop the ball.
