I am living proof of the other side of the coin.
With my swing (~105 with the driver) the 10* driver ballooned on me and I lost all roll after my drives. I tried the 8.5* and had long, boring trajectory that I had always longed for.
That being said, it wasn't with the Taylor Made. When I hit the TM580 last fall, I never seemed to be able to hit anything but pushes with it. I never could pull it over the top and hit a draw. I find the heads on those things enourmous, but that's just me.
Are you hitting just hooks or are you really duck hooking it? It could be that your hands are fast and you're coming over the top. I personally don't think that the loft of your driver (it's 2 degrees difference) is going to make you hook that bugger like crazy. Are the shafts the same? Sometimes OEM shafts are just terrible for consistency. Perhaps an aftermarket shaft with a more moderate torque would work for your particular swing.
In the end, you might want to go get fitted again. Sounds like you were sold something that isn't really working with your swing. Too bad.
