FWIW, I use an 8" white Norton wheel. I like the flatter shape of an 8" wheel, but I doubt it matters much. My grinder can run as slow as 2000 RPM. So the edge is moving approximately as fast as a normal speed 6" wheel (feet per second rather than RPM). The hollow grind was a game changer for me. It's so fast and it makes maintaining the secondary bevel dead simple.
Chisels and flat plane irons are easy. I still struggle to create a smooth curve on cambered irons. Mostly I grind them flat and work the edges on the stone by applying pressure to the corners.
