i bought a wheelset a few years ago (rhyno lites w/ mini profile cassettes). maybe a month or 2 after i bought them, i fell at the tarheel national in north carolina and the rear rhynolite pretty much exploded. i replaced it with a bfr and it has held up fine. the front rhynolite has held up just fine. so, just don't all really weird on your rhynolite and it'll be fine
