The CT 250 was my gamer and still was until the ISO-T came out. This year, I am putting the TC Driver in play. Could swap between the ISO-T and TC with no problem, but for me, being able to adjust the TC to a more open face angle with a lower loft setting works, and I like the look. The ISO-T 9.5 was the first driver I could use since the CT250 (8 deg. loft) that gave me a similar trajectory. The cg in the ISO-T allowed me to hit the 9.5 and not hit it too high. It also sits really square, which is good. The TC I am able to tweak the loft slightly lower and get the face angle slightly open, which is what I like. The TC looks bigger, but both are basically the same size. The differences in the body and crown shapes create the different look. The face heights are very close, with the TC being only a few thousands of an inch taller. Performance, both are great and both have a great sound, in my opinion. Don’t think you can go wrong with either. The TC is the newest and has the most versatility because of the adjustability.
