We would only be guessing without seeing your swing on a launch monitor. The TSi1 and TSi2 are very different and not just the heads. The standard shafts make a big difference too. Nelly Korda plays a TSi1 but not with the Aldila Ascent shaft. Also factor in the different lofts and there are quite a bit of combinations that might best fit your game. A proper fitting could save you $$$ in wasted money if you have to keep trading to find the best combination. Hope this helps.

The only way to tell is to hit 'em both TSi 1 was best for me.

It does vary based on your tempo as well. At 85 mph, I'm just in-between. I have a TSi1 head and the TSi2 shaft. The stock R2 shaft was creating too much spin. It was running towards 4000 rpm backspin.

Also, you have to look at dispersion. If the club is too light, you may end up with a wider dispersion pattern. I wouldn't buy either with a fitting with both. But one of these will be right for you.

TSi1 comes with the lighter Aldila Ascent shafts. Even with your speed, It could pull left more than you would like. Putting in a heavier 55 or 60 gram stock tensei blue could work. I would suggest getting to a fiter with a launch monitor and try them out. You will be glad you did.
