If your a beginner, start off with the solid wheels made by GRP, they are the parent company of Elligi, Fast, Arrow's, Treads, Action, and a few others. They last the life of the rubber, and will not break.
Associated uses Jaco's because they GIVE them to them. they're the MOST FRAGILE WHEELS I"VE EVER USED. not to mention their price.
Give Lee a call at Winner's Circle
he carries Elligi and Fast's with a good price.
