Hello ... I have the 900 Forged as well - One of the (many) things I like about the set was the compact size of the short irons, including the wedge - Based on that, when I saw there was a GW available, I thought I'd died & gone to heaven, so I ordered one - I had not been able to see one before I ordered, and was very disappointed when it arrived - It wasn't anything like the size of the PW, and I put it straight on eBay! - After a chat with my Pro, I opted for the 50* T7 wedge, which is much more the size I was after & blends in nicely with the 900 Forged (imho)
Hope that helps & if nothing else suggests (if you can) try to see the club(s) you plan to buy before ordering them?
Paul
