I did a Titleist iron fitting about 6 weeks. We had some time left and the fitter asked if there was anything else I wanted to try. I mentioned that I had been thinking about replacing my 910h (I think it was 19deg) and he suggested trying a 7w. As soon as I hit it, I knew it was the right decision.
Fast forward to last Friday. I played in a scramble with some friends and had several opportunities to use the new 7w. After hitting some really good shots, a friend started asking me about it. I offered to let him try it for our 2nd shot on a par 5 and he flushed it. He turned to me and said, "Oh yeah. I am definitely getting one of these!"
If you are looking for something in lieu of a 3i, I would highly suggest giving it a shot.
