i'm looking to convert a pair of nike skates to inline , and just bought a bunch of chassis (lot sale on ebay LOL) .. and looks like i'll be able to use TUUK rockers ..what size wheel configuration these run ? i'll be going back to europe and the surface of "choice " ( not other option :P ) is asphalt . i've always played ice , and it's what i know best. what you guys recommend as far as wheel configuration ? i only skated couple times on roller when i was young and i hated it , bc they were cheap and very different than ice . i've played nation team and college hockey ..so i'm not too bad on ice :P pleas ehelp me out here -- to feel asphalt as close to ice as possible ! TIA
