I think the runs you get when presenting the gouge are a result of the cutting egde not being perfectly neutral at the point of contact. The assemetrical grind effectively makes the cutting edge shorter on the swept back side of the gouge. When the edge makes contact, it is at an angle to the rotation, and causes the gouge to skate. Brute force to hold it in posititon until there is enough notch for the bevel to register against is one way to control the skate. When I try using brute force for control, it always fails me at the worst time. You might try closing the flute a few more degrees at entry to bring the longer part of the gouge into a more neutral mode and then open the flute after the cut is established, or, try grinding the conventional side of the flute just a bit shorter. Grinding that side of the flute a bit shorter will result in the portion of the egde making initial contact more neutral and less apt to skate.
I do see the advantage in having the right side of the flute with a more blunt bevel, but I don't think I am going to give it a try. I keep a conventional grind with a blunt angle in the tool rack for those parts of a bowl that need it.
I also see the advantage of using the soft spot of the belt to get a convex bevel for use inside a bowl. I see no advantage of a convex bevel on the outside of a form though.
