First off, is it real stingray or imitation?
I've got a stingray saddle (and an ostrich, and a gator, and a couple suede). It's a little less slick than the ostrich and a little more slick than the gator and suede. It has kind of a plastic feel to it, lots of little bumps. If they don't put a bunch of padding under it, it tends to be hard. It's not terribly slick, but if you do want grip, then it's probably not the best thing--or at least pair it with roughout rather than slickout leather. And if you wear jeans with crystals, studs, or buttons on the pockets....you'll be making quite a sound as you ride and rub against all the little ridges.
