I still use an old Wilson Deep Red 10.5 degree stiff flex shaft driver that I bought for like $65 a few years ago (bought a couple more like $15) during a clearance sale.
This picture shows a 400cc driver, I have the 360cc.
I've tried newer, higher-tech, more-expensive drivers and they can't compare.
The angle isn't conducive to bomb drives, but if
I can hit it 300 yards (which I've done on at least a couple occastions), maybe you can get it to 330.
