The deal I found on these was from 4-AW. I've dropped the 4 in favor of a hybrid and substituted a MD2 50* for the AW to go with my MD2 Tour Grind 54 and 58. For some reason I can't get any distance out of the AW that came with the set and prefer the turf interaction of the MD off some of the tight fairways I play.
I game 5-AW and have noticed the same with my AW. I havent checked lofts on it, but my AW seems short compared to my 50* wedge (also a MD2), and i have since switched them out.
Sounds like we have a similar setup! I go hybrid, 5-PW, 50/54/58. it works!
