"In a similar vein, sure, I'd like to trade my daily driver Supershapes for a RX 70. But for what advantage? I can hear Phil smiling at this marketing opening."
I kinda did this. ?I sold you my Supershapes and last night I mounted up my RX70's... ? 
Priceless! Hey, enjoy them! Everybody needs at least one pair of Kastle's.

A Phil purchase? Talk about 6 degrees of seperation. I knew Phil, who knew Ron, who Gary, who knew Greg, who posts on Epic sales.
Actually, I'm still smiling at my Supershapes performance and the cost/benefit analysis made our deal a "no brainer". The box and shipping peanuts Greg shipped them in was worthy of shipping a couple of pair of RX 70's. Nice east cost carver! Keep them on edge and they hold speeds pretty well.
They took a major hit yesterday when I got plowed into during an instructional clinic. Need to epoxy a square inch of topsheet and file out side edge indentation. My body survived better than my skis, somebody up there likes me better this year. I ended up about 60 yards below my skis, and, the person who brought them down to me though them as "heavy". They are , but, not on the feet.
