It's true, my first gen TRS btx actually has camber from bindings to tip. I was just messing around with my long wax scraper and noticed space when I placed it lengthwise from the banana center to tip or tale... They've obviously been evolving the shape because the cambers weren't as pronounced as my C2 T.Rice, but more importantly, my TRS didn't have the slight convex base that my Rice has.
Interesting, which year rice do you have? '10 or '11
