Borderline not on topic, but I ended up getting rained out bombing a relatively mellow hill about a year back, and I was using those cheap Indy bearings with a metal shield. Immediately after the session they seized up (as one would expect), and were nearly unridable. It was the only board setup I had a couple hours from home, so I rode through it till eventually they loosened back up. Now they are one of the fastest set of bearings I own. I don't understand why, and I certainly would not recommend them to anyone, but somehow the rain and dirt caused my bearings to improve.
That's my shit story, and now I too wanna build a rain/snow setup.
