Damn thats expensive as fuck, I'm glad I'm not in Canada.
STH 14's would probably be fine, well not probably, they would haha.  Even Griffons if you want, at your weight/height they should be fine for you especially with Bibby's which aren't really a charging ski.
I'd mount them like -2 from center probably.  Just because it will help them float, then again with the rocker they might be fine at true center or -1, but we're talking centimeters here so it's not going to be a huge deal if it's -1 rather than -2 or whatever.
