I just purchased the t150 7-p and t200 4-6. The 200s being more forgiving allowed me better numbers when getting fitted. It’s all personal preference but the yardages also worked out great.

I just got fitted for T-150s and planned to blend with T-200 5 and 6. However, there wasn’t any substantial gains. Going to T350 gain yards but lost spin and widen the gap between clubs. Ended up with 5-pw in T-150. Going to add a 7 wood to fill the 200-220 range.

I may be the odd man out, but I ended up getting fitted for a T350 4 and 5 and T150 6-W. When we tried T200, they spun too much and didn't really cover the ball speed gap for me. The lofts on the T350 were adjusted just one degree to make the gapping a bit more consistent

I am currently playing T200 18deg, T100 4 to PW. AMT Black reg, Vokey 50/54/58.
Looking at swapping out 8/9/PW for MBs. Played pure blades for 30years and MBs prior to T100s, prefer feel of the MBs 150yds in.
Could I ask how you are looking to blend the shafts in across set ?

I was fitted into a blend with T200 5-7 and T150 8-P plus the W. I have also tried and am happier with the flexibility provided by a REAL pitching wedge, a Vokey 48* instead of carrying the W. A full set of T200 probably wouldn't have been a bad option either, but I do like the looks of the T150.

I'm at the game phase where perhaps it doesn't make much difference in the short irons whether I use T150, T100, or even CBs. I've even considered going back to short iron blades because when I hit a good shot, I want to know it was ME and not the clubhead!
