It’s never too soon to upgrade! Just kidding, of course. It really depends on if you need the added yardage and dispersion benefits, which probably isn’t that significant for the average player between the TSR and GT. But for some, a little goes a long way. And truthfully, some of us just want the latest and greatest. Nothing wrong with that. Lastly, if you bought the TSR without being fitted, you could see tremendous benefits from being fit into a GT.

If you are consistently in the sweet spot of your pictures, and were fitted into the TSR, you might only see minimal benefit.
You just need to decide if you only want a new driver or you feel you NEED a new driver. Don’t use us to justify to your significant other that we said you need a new driver.

All these choices are up to you! I am not sure you would see a huge change in numbers from TSr to GT, but there will likely be a gain in speed. How much is that worth to you? If you want more ball speed and got the money... send it!!
