I’ve got the Nippon Modus 105 in my T200s and love it. I had that shaft in my prior iron set as well.

I went with AMTs in my new T200s because I played them in my AP2s and AP3s and had no complaints. I hit both the Nippon and AMTs and didn't see any appreciable distance difference. I like the heavier shafts in the short clubs for more accuracy, while having lighter shafts in my longer irons, which theoretically, should translate into a slight increase in swing speed.

Frankly, once I dial in my T200s and have my swing working normally (better than I did that particular day I got fit), I expect to be refit by an excellent fitter I know who has been fitting on the PGA Tour for years, whose expertise I trust explicitly. At that time, I may consider different shaft options of which were not available to me through Titleist as standard offerings. But, for now, I don't feel like the AMT Blacks I ordered in the T200s will be hurting me at all. They are nice shafts that feel good to me. I have hit the Modus 120s in both the new Titleist offerings, as well as in a friend's new TM 790s. Hated the 790. Don't know if it was due to the iron or the shaft, or both.....or the fact that it wasn't Titleist! Probably the latter. ;-)

For the record, for comparison purposes, I'm presently a 4.9 index with 94-97 mph driver swing speed, and hit my 7i between 150-155, 160 max.

Enjoy your new T200s.

Nippon Modus 120 is a heavier shaft and has a mid launch. TT AMT Black mid/high launch. My favourite is the TT XP95.

Which shaft produced the best numbers and got you the results you were looking for? When I went for my fitting I told my fitter before I got there I wanted a new club that would get me a straighter flight, more height, more distance, and less effort. We tried the T200 and T300 with a multitude of shafts. Based upon the numbers off trackman and the actual on range results, we decided that the T300 AMT Red R300 107g-95g met my goals. We were able to get me to 160 yards with the 7 iron with ease. I had been playing 716 AP1S xp105s S300. At 73 I finally gave in to regular shafts and they really feel great and I do not have to work as hard. Which one feels best and gives you the best result?

Wow, surprising since they are two distinctly different shafts. Were you fit for both at the same fitting and did you use the same fitter? I guess you'll need to decide which gave you the best performance during your fitting(s).

Were the numbers from the 2 shafts identical? Not just carry and overall distance, but things like launch angle and angle of descent are key to good scoring. Were strike patterns or misses any different between the two? If the numbers are identical from the fitting then I would tend to go with feel.

I'm surprised that you were fitted for a 120 gram shaft in a regular flex. I would have thought that the 105 Modus would be a better fit in a regular. I do find the Modus to have a slightly better feel and a bit less spin that the AMT. But our swings are different and that could be the difference in the numbers between the shafts.

If the numbers are the same, I would go with the better feeling shaft.

I was originally fitted for the Modus shaft with a strong right to left wind blowing accross the range, it gave a better ball flight than the AMT I felt that the Modus shaft was recommended for that reason, I do understand his reasoning. The AMT gave a slightly higher ball flight not really any more than the Modus and also performed well in the wind so not much difference in my mind to worry about.
I later had another fitting with my local pro, the only problem was that he was unable to get a Modus shaft as it was an upcharge shaft, the AMT with no wind performed very well. So I'm not sure whether to try and get another fitting with the Modus or to go ahead with the AMT as there isn't really much difference in the numbers.

Probably wouldn't hurt to do another fitting so you can try the Modus 120 again (hopefully with less wind).

Did the fitting utilize just one club (like maybe 7-iron) or were you fitted throughout the whole set?

The reason I ask is the Modus 120 is constant weight (111g) while the AMT Black are ascending mass (94-115g). That means in the longest clubs like 4-iron the AMT Black will be much lighter than Modus 120. In the shortest clubs like 9-iron they are virtually the same weight.

In the 6-iron or 7-iron the AMT Black is slightly lighter. I prefer variable weight shafts as the extra weight in the short irons helps my tempo.

Yes it was just a 7 iron and I am aware of the different characteristics of the two shafts. Because of the variable I do slightly favour the AMT.

Anyone try the AMT white in the t200s?

Had them in my AP# was ok with the shaft but I went back to the project x chrome in my 620 CBs'...just a better feeling shaft for my swing.
