A paved runway??? FOR REAL?? You have actually seen one?? I've heard of them, but never actually SEEN one, I thought they were merely legendary beasts like the Yeti and the Sasquatch.
Actually, for grass, I just use the BIGGEST foam wheels I can fit on the plane without looking totally ridiculous, (slightly ridiculous doesn't bother me) ( I use 3 inch foamies on my little 15 oz 36 inch wingspan electric) I make sure that the landing gear has a fair amount of spring or give in it, and go forth and play.
Having said all that, I fly off a pretty rough strip, and don't have any landing gear problems other than occasionally having to re-form the legs after a particularly hard bounce.
