you will be very unstable on them. i skied on my friends 161 flyers and i am 5'10" and i could barely make it down the hill. i would never ski on anything shorter than a 170. if you want something shorter, get like a 165 at the least for playing around. ur tall so you could ski a 170 like its a baby ski. but you will have teh worst time on a 161 and even worse on a 151. dont waste your money
