My bro is starting skiing next year. He started this year and wasnt too bad.. was sliding 10 foot rails on the first day. hes about 5'4" - 5'5" and 130 lbs. My question is Ive got a pari of 158 lines or 167 rossis, height wise Im thinking the 158s but weight maybe 167s.. I ride 176s and Im only 145lbs
