If you had the opportunity to change your grinder, or dream of a grinder, what SFPM would you want? 5600, 4700, or 3700? I am debating on what size drive wheel to get. I guess if I really wanted I could get the best of both worlds and get the 4 and the 6". I have a VFD so I have speed control.

If its rough grinding you are talking about, I'll take the 5600 with ceramic belts. They work most efficiently at the higher speeds.
Ceramic belts, in order to get the best removal of material, need pressure as well as speed.
The ceramic crystals shear under pressure and produce a new cutting surface as they do this.
Since you have a vfd you will be able to get the lower belt speeds which are needed to use the finer grit belts.

Get the six inch wheel and you will have all the variables you will need.

I go from 1000 to 5000, and that is about right I think.

3700 ain't enough.
