While I was underneah my boat last night resounding the hull I noticed
that my trailer rollers are needing some stuff done to them. Some are
cracked and flaking, and others have the center support bushings jsut
plane gone!

I've seen both rubber and polyeurathane rollers offered by various
suppliers and there's nothig cheap about them especially when I'm
considering replacing about all of them.

Rubber seems to be the most economical way to go. But is there some
advantage on why I should go with the poly?

Poly rollers are available in red and yellow. They look like they're
made out of jell-o, but that's beside the point.

I'm voting on going with the rubber, because after all they've been on
this trailer since 1977.

But anyhow. what advantage do the poly's have over the rubber rollers
if any?
