GT DRIVERS

From what I’m seen the
number of the TSR driver will correspond to the GT.

You get fit each time you get a new driver. There is no way to say which will work best for you without actually hitting them with the assistance of a certified fitter.

Like Brock says, the only way to know for sure is by doing a proper fitting. I was in the TS3, TSi2, then back to a TSR3 and had a quick fit into the GT2 at the TTI FOH event. I will still do a full, detailed fitting for GT and not force the final outcome. BTW, they will likely release a GT1 in the late winter or early spring.

Without knowing how well the TSI-1 works for you, you might want to hold off until the GT-1 is released Until then, you can only get fit into the -2, -3, or -4. One of these might be a better fit than the TSI-1 but you won’t be able to compete to the GT-1, yet.
