I'm now looking to upgrade my slow-speed grinder for lathe tools to CBN Wheels. Any recommendations on Wheel Brand, Grits, and other potential issues related to them? Websites would be appreciated. Thanks, guys.
CBN Wheels ?

I do not use them but the big thing when switching to them is they are heavier so torq speed is important. 1/2 HP motor is still questionable. 1 HP is better. If buying 2 that is adding about 10 lbs so secure platform is a must. For turning tools 8" is best. Costly yes. To me unless you do alot of sharpening I am not a fan. I am sure others that have them and use them will chime in. But starting speed is a concern or else you will burn motor. Many times people overcome it by spinning wheel by hand to start.

So, woodturnerswonders is a great company who carries numerous cbn wheels.
While they are heavier, the newer style aluminum ones aren't too bad.
They come in all sorts of grits and profiles. You can get flat, narrow style like your current white, stone wheels or get ones with a radius edge. They also have ones that have a flat area on the side of the wheel. The only hiccup is sometimes your platform won't be wide enough for the larger ones.
I've had 2 cbn wheels on my rikon grinder, I believe it is a 1/2 horse, for years with out issue.
The rikon 3/4 grinder with 2 cbn wheels is a nice platform and quite useful.
I like the mega square wheels, they are 1.5 inches wide and dont have a radius edge.
I would go with an 80 grit for shaping and rough profiling and a 320 for touchups.
You may also want to invest in a decent platform. I really like the Stewart Batty ones (sbtools) (I think they are still made). You can get them in either free standing or ones that fit the wolverine style system.
If you use a jig for sharpening, you can't beat the varigrind from wolverine.
I also really like the raptor setup gauges, however sbtools has a nice set too.
