You and I must be of similar age (1976-1979, 1983- present) - hahaha
I too had some of the first urethane wheels (OJ's, Kyrptonics, than later on it was multicolored Val-Surf wheels on Tracker trucks. I used to compete in basically 3 events, freestyle, slalom and high jump. I also used to have a 42"longboard for laying down "coffin-style" and going down hill. My other 2 boards were a G&S FiberFlex for slalom and a Val-Surf 30" laminated maple for freestyle.
I don't skate regularly anymore because I don't have a board now, but whenever I see a kid riding incorrectly, I'll usually offer a little instruction. They're more amazed at how I handle a board than the actual advice that goes unnoticed after 100 yards - Hahaha
