Buying a single line of clubs, I always seemed to have one too many long irons that didn’t gap well. Fitted this time to 7-48 T200 and 6 T350, the 6 keeps the gapping distance I need. I then go to a hybrid to keep the same gapping.
You only need a blended set if your last iron (3 or 4 iron) still has 5 mph more ball speed and a similar descent angle of your 4 or 5 iron. Which is what the vast majority of us need. The goal is to be able to control the flight into a green with any iron. Let the fitter find the best match.

Incredibly helpful, thank you Don!!

I have a T100S/T200 blend (6-pw & 4/5). The T100S and T150s were essentially made to blend with the T200. You may run into some issues trying to blend the T100 in with the difference in loft.

I know the T150s aren’t exactly like the T100S, but curious why you want to try and blend the T100 as well. The T100 and T100S are essentially the same, just 2 degrees stronger

Thanks, I don’t “want to” I’ve just been thinking about what it might add. You make a great point on the T100s and that’s why I posted, to get some guidance from you all (which I appreciate). My ego wants to be a T100 guy, but fitting showed T200 through the bag makes the most sense for me….

Just got fit for a new set and they are mixed. 5 - 6 irons are T350, 7-PW, GW are T200

Seems to be the latest in Titleist irons and players are getting better results. Maybe why the T series irons are now forged (except the T400).

I run a blended set of 620 cb/mb 4-Pw and couldn't be happier. I also run a T200 3 iron as a driving iron. This setup, for me, will be in the bag for quite some time.

I have always done blended sets..very good way to go…just need to match up lofts…
