I switched to the SuperQuad from the Nike SQ last year and I love it! I actually own two (8.5 and 10.5). I purchased the 8.5 last after a fitting on TM's MATT system. I decided to keep the 10.5 just as a backup (for tournaments)
The last favorite driver I had was the old TM Firesole, but when I snapped the shaft at the hosel the search began for a new favorite. The search has finally ended after about 6 years of searching!
The SuperQuad to me is just solid. I haven't really played much with the weights as I would rather shape shots naturally as opposed to "mechanically".
