I buff all my NE bowls, and I make a lot of them. I have the 3 large Beall wheels with an extender. You learn very quickly how to do it, it only takes one bowl flying out of your hands.
Well, I guess I'm a slow learner, because I lost at least three or four bowls early on!

Haven't lost one in the last five or six years, though.

Until you figure out how to best present the bowl to the spinning buff, it's a very good idea to have a pair of light duty rubberized work gloves with the fingertips cut off. The gloves work so well, that they're part of my regular routine now.....gives a real positive grip.
The Beall system works well, and I have no plans to change to anything else. Use the EEE (Tripoli) and WD (White Diamond)
sparingly, and you may want to eliminate the WD for some very difficult woods.....like burls with voids. At other times, just using the WD wheel with whatever is left from the previous use, is also a good option. The WD tends to embed into voids, and looks bad. A stiff toothbrush helps, but it's much better to avoid it.
I remember the Beall instructions saying it will take out small scratches.....but, that is pure fantasy, from my POV. It's best to refine your sanding technique to the point where you only have to think about getting a good looking buffed surface.
All the buff sizes are in my inventory, but the 8" wheels and 4" bowl buffs are, by far, the most used buffs. Don't know if it's still available, but there is a 4" extension that screws directly into the motor mandrel, making it an 8" extension overall. I don't use it very often, but it's handy to have on occasion.
I initially buffed on the lathe, but that was quickly replaced with my homemade buffing station. I used an old Leeson 120v lathe motor I had on hand. It's 1.5hp, and that's way more hp than what's needed, but it does work beautifully. 1725rpm works very well, although a variable speed may be an improvement to overall performance. Still, I'm quite satisfied with my buffing station as is, so changing to a variable speed isn't very high on my list of things to do!
