I typically use either Onsrud or Vortex ( Vortex Tool: Solid Carbide Router Bits and Compression Spirals for woodworking, plastics and non-ferrous industries. )
At 10,000 rpm, 8M/min sounds like a good start. You might even start with your FRO turned down a little, and work your way up to the 8m/min I don't have any experience with a low speed spindle like that.

I have used wood roughing bits, and as Dean says, they do cut like butter. But I don't think that you really need one. I can suggest not cutting MDF with the bit your using on OSB, as MDF will dull the bit a little faster.
