I've run Proline and the Advantage rims. Proline is definitely proud of their wheels (expensive) but the hex area is pretty beefy as are the spokes. The Advantage rims are about half the price, but the hex area is not nearly as beefy and the spokes a definitely thinner. I did manage to get a hairline crack in the bead area too. I would say that on high-bite tracks, the Advantage rims wouldn't hold up well; spun hexes; tweaked spokes, but for the loamy, loose tracks I run on, they're acceptable. Dish-style wheels may fair better.

I've never run JC wheels, but they're a reputable company and I would imagine their stuff would hold up quite well and is a good compromise between the expensive Proline and the bargain basement Advantage stuff. Never run Kyosho either. Just don't like the look of the slotted wheels. Although, since when did "looks" win a race?
