you'll have difficulty getting a set of 020's, they've been discontinued and replaced with 021's which they currently don't do a front for the strom from what I hear. I can tell you they won't last 3 times as long, prob last less time than the trailwings because they are a softer compound (well technically dual compound) I liked them on my vfr but I prefer the trail type tyre on the strom and they seem to give as much grip (to me anyway)
have a good browse through the site, lots of stuff about tyres and different options available
Oh and personally I'd get the tyres from someone else, he sounds full of crap
