Seriously, the rolling resistance is decreased with the new belts, but I doubt it's worth the trouble to fabricate a belt guide. The obvious answer is to mold a collar on the port side of the pulley.
Jack, use the side flange collar from the oneway pulley on the ball diff. That's what Art Carbonnel uses.
It's strange. Sometimes I find my ordinary belt also wants to slip out with a front diff. But now, I don't find that problem even when I run with that flange collar from the oneway front pulley. Perhaps it's slightly got to do with the front bulkhead alignment or the ecentric cam...
Concerning the PRO belts, I would use them on a clean track but the track we run on tends to have pebbles here and there. So far I'm very happy with my standard kevlar belts. All 3 belts have not been changed since early January this year. And most of all, I particularly like using the 6361 from the front of the Vector / 950 1/8th scale belt as rear belt.
