I've been using a 188 rustler 11 with guardians for doing some sidecountry around Lake Louise, great skis but a bit ridiculous for uphill. Looking for a lighter set-up for Japan, maybe a bit "surfier" than the rustler but still able to charge pretty hard. Will mount with shift bindings. I'm 6' 190lbs. What kind of waist width do most people have for touring there?
