just don't go through 'em. The turbulence around them generally isn't any worse than the convective stuff you get off the desert. I've been sitting with one wing in the cloud trying to stay VFR and the ride isn't particullary bad or scary....and most of those were level 5 TS's. I popped under a roll cloud once...wouldn't recommend doing that...but the NT guys could probably give ya a few tips.
