yeah right...wheels don't matter, until you're laying over a turn at close to 25 miles per hour and you loose traction in the back and go skipping across the pavement like a ragdoll.  Like someone above said, wheels, bearings and trucks are the most important parts of your board, i'm on 80mm abec 11 fly wheels with bones reds bearings and randall trucks.  They're dope.  The actual deck is just a piece of plywood with some fiberglass in it, unless you're getting a loaded or landyachtz dh race they'll all perform about the same depending on flex, stiffer = more stable, softer = quicker turnier, just like skis.
