First off, thanks for sharing that picture as your avatar. When I saw it, it brought back great memories with my son... THANKS!
To answer your question, I never played pro ice (I hate the cold) just inline. I played through the Southeast on different pro tournament teams. I was what one would call a 'mercenary player'!
I thought I saw the wheels. I had a bunch of friends that played on the MN Blue Ox and Arctic Blast before they all folded up. I never could get into inline, too many accidents with the boards at high speeds. Plus ice time is easy to get in MN.
