I have played Titleist MB irons for 30 years. Most recently 716MB. 6 months ago I tried the TMB 2 iron. So impressed I added 3 and 4. The results of high launch, extra carry and mostly the extremely straight trajectory caused me to complete the set with 5 thru 9, p and w. I am 74 and can easily hit the 2 iron 200 plus carry. I realize that's not impressive to the younger crowd but i assure you my similarly aged buds are impressed when I regularly blast the 2 or 3 past their drivers on a very tight fairway. These irons are awesome. The only reason I can think that many Titleist staff are not playing the full set is that these irons are frankly difficult to draw and fade significantly. They are as good as designed. Expensive but if you value quality and results, try the T-MB's.
