Bread-Bakers v103.n029.4

I recently did the somewhat insane thing of buying a 20 qt used Hobart 
mixer without really knowing what I'm going to do with it. It comes with a 
paddle and whisk but no bread hook. I know there are two types of hooks: 
the standard J hook or a more curvaceous Spiral hook. I'll probably be 
making bread dough. Does anyone have any recommendations?

Thanks,
Bonni
