The prophet 90/100's are both sick. totally solid skis, stiff though. I got last years blend, and its pretty dope 9same dimensions as the prophet 90, but different construction, so its a little softer, and better in the park. I love them. This years are sick too. I weigh 175 and I'm on 179's (which is actually longer, with line skis) If i were you i'd go either 179 or 186, depending on your ability. But it sounds like you need 179 based on the way you worded your post
