Good evening all, and Merry Christmas!

Following a fitting at Wham Golf, I now have a GT3 Driver, but am struggling with it a bit, my good shots are definitely better than previous, but I am having some that are just 200yd worn burners, or even worse off the tee, feeling like I hit it with a bag of spuds. Unfortunately, my pro is off sick and I have 3 games before any possibility of getting on Trackman to see what the issues are, will give details below, and any quick fix ideas are very welcome. Having got desperate, Chat GPT has suggested increasing tee height and adding 2-4g of lead tape to the bottom / rear of the driver. I am nervous of teeing too high and skying my unblemished driver, but it does feel like the easy solution.

New driver GT3 9 degree, D4 setting increasing to 9.75. Tensei 55g Blue 1k shaft. Old driver TS2 10.5 degree, 6.0 Hzrdous Black

Swing speed is around the 100-105moh mark

Thanks for your help!
