I play 3 heavy drivers at the moment - rogue sz, 203 grams, 78 gram shaft, 46.5", callaway octane 212 grams, 45", 90 gram shaft, titleist 975j, 43", 210grams, 90 gram shaft.
My experiment started with an m1 head last year, I was bombing the 3 wood so i figured I would build the driver to the exact same specs as the 3 wood, same shaft, same length and same headweight. It was okay for awhile but ultimately i just could not get used to the 460cc m1 head on the short shaft, plus i generally play overlength drivers (47"), so just could not get used to it.
I would recommend getting a driver head that you can buy a weight kit for to experiment with different weights easily and then build your driver like a 3 wood (210-212 gram head) at about 43" or maybe like a 2 wood (205-206) gram head at 44" with a heavier shaft - this is based off a standard driver head weight of about 200 gram at 45". Ideally you would have an adjustable driver that you could swap shafts easily too so adjustments could be made easily at the range or on a launch monitor.
For me, heavier drivers are more consistent at the expense of some distance. So have fun, and now you have an excuse to ho a driver head or two and some shafts lol!
Good luck my friend!
