I have one laying around, and maybe they should include a how to with them. I was/am in the same boat. I found actually drawing it cross grained like a knife with a straight blade got me the best result, but it did require a LOT of pressure, and wasn't restful at all. I don't think I will ever need to learn to sharpen it.
I too reverted to a selection of gouges like Nathan is showing in his pic. I find them much more restful/relaxing to just tap, and work them in to make a spoon a spoon. Unless I am looking for speed, then I break out the grinder with the Ball gouge mounted. I really need a better bench than I have, something with more meat to hold work while I kick it's azz. :-)
