I went to a Titleist fitting yesterday and was fit into the T250's 5-P with the AMT White S300. I hit the T150 very well also, and was hoping I could maybe jump into that category but the fitter recommended the T250 based on the distance I was gaining.
I gotta say, the two clubs look nearly identical at address as it was really hard to tell the difference. I have a 7 iron swing speed of 82 and was carrying the T250 about 8-9 yards further but with the loft difference of 1.5 that should generally be expected.
I also was disappointed they didn't have the AMT Silver as that is the "stock" iron on these 150's so I would have liked to see how that shaft compared between White and Black.
