So AI tells me stock Stealth is 45.75" long. Which is pretty dern long. Not sure what shaft you have, and of course if you cut your diver down a bit it's fairly permanent. But if you pop the grip off and cut an inch off, with a Dremel or some other tool/saw, and put another grip on, you'd need to add about 8 grams of weight to the head to keep the swingweight the same. Pretty sure you can get heavier TM weights for the Stealth driver.
Anyway, not telling you to go do this, but that is the gist of it. You can always choke up an inch to get an idea before doing anything drastic. And could even get 8 grams of extra TM weights to try that with.
My Titleist would have been 45.5" with a stock shaft, but I use the 43.75"shaft I already had which comes out to 44.75" when installed in the GT3.
I find it's just easier to make a good proper swing with and control, plus hit in the screws more often.
Of course you could try 45" for a starters, before going any farther. I took .75" off and needed 6 grams. I have a swingweight scale, and yours should be similar.
Awesome stuff. Definitely going to tinker with this. Thanks.
