Should I go to the importer/distrubutor, or is there another souce for these wheels with the proper bearing sizes?

PS: The reason I ask: I would like to change to BFlights for the beach days, and back to barrows for dry lake/grass days. Is the best way to have a set of wheels for eash, with tires already mounted? Or is there another way?

I'd suggest sending a U2U message to TexasBuggyRider, coreykite or WindWiz and get yourself a couple sets of wheels/tires for each surface you mentioned.
