DLR wheel bearing ?'s

[288sunny]

Just curious if the DLR tapor bearings are the best of the best. Been riding here in West VA for a few days, on the hatfield MCcoy trails and tons and tons of mud holes, puddles, etc. So the wheels have been in lots of water. Are the stock bearings meant to handle this kind of stuff? If I was to switch to DLR tapor bearings, since there not sealed but can be serviced can they handle lots of water and last, If I had DLR bearings i would plan on repacking the grease every year, maybe even every 6 months. So give me the pro's and cons and what would be the smartest move, go with stock or DLR bearings.

How hard are they to install?

Also curious about the rear axle bearings and the bearings where the swingarm mount to the frame?
