I have played the T100's for almost a year after playing blades for over 15 years. Absolutely love them. I feel like I hit more good iron shots in the past year than I have in the previous 15 combined. Lol. The feel, look, trajectory, distance control and very underrated turf interaction. The good shots feel like my old blades, the margin of error is a lot nicer though.

It's best to go for a fitting with an open mind to model choice.Let the numbers produced on trackman or other launch monitor show what's best.
I went to Titleist National Fitting Centre at St. Ives,Cambridgeshire.

I tested t100,t100s and t200.

I hit them all ok but the numbers on trackman showed t200 as best.

Went ahead and ordered them and they feel awesome.

Love to hear feedback on this post also.

I put T100's in my bag about 6 weeks ago, replacing a set AP2 714's.

Honestly, I didn't consider/demo any other irons. I went to a Titleist Thursday at a local club, tried a few different shafts and never once looked at Trackman stats. I ended up ordering the T100's with the exact same setup as my AP2's - if it ain't broke don't fix it.

Six weeks and probably 20 rounds later, my index is at an all time low and I couldn't be happier!

Ended up going with the T100/S irons, 56/52 Vokey wedges and TS3 Driver. I was extremely happy with my fitting and these clubs went through the grass like butter. I had about 5-10 more yards on all my clubs and hit them much straighter. Looking forward to getting them in a week and my first round with them!
