Since you're still "new" to racing, and not that big of a guy, I wouldn't go past a 120/130, really. As soft as they may feel in the show, they'll be stiff on the snow, especially when its 25 degrees outside, not 70 degrees in the shop, which makes a huge difference. Just keep that in mind when shopping for boots, and as someone new to racing, don't think you immediately have to jump into the stiffest things, because it will hinder your performance.
Stiffer != Better
