What's the best driver to throw to practice accuracy?

I like comets but what I'd really suggest is some warm up.

Create your putting circle short of your dependable distance.
Using your entire bag, try to land in your circle using every shot you know- and some you don't know- to get there. So annys, spikes, fh's, rollers, etc... Obviously, distances would be disc and shot dependant so don't feel bad moving up a lil.

Comet. If you are changing your throw at all the comet will show you.
I do not use one in tourney play, but they are great for seeing your mistakes in a practice field..

This is true, Comet will show you right off the bat what the issues are. I hyzer-flip my zcomet and throw alot of straight shots with it but it must be finessed.
