You want synthetic. As far as wet goes, no grease is going to do well after it mixes with water and I have not seen a grease that won't. Yeah, they're resistant, which means they'll mix with water, but will try not too. /forums/images/graemlins/shocked.gif Anyway, all bearing I've seen on late model equipment are well protected. If you submerge a hub, plan on pulling your bearings down and servicing them promptly. In the synthetics, all that I've used have been excellent. Just get pure synthetic and none of that mixed crap. Also, it's a much thinner consistency and kind of a pita to fill the hub halfway, but the mess is worthwhile. Good luck with whatever you choose. /forums/images/graemlins/smile.gif
