I am 5' 8" and have 183 bentchetlers. i have them mounted just ahead of the team line (about 3 cm back from center) and ski pretty aggresively and i almost wish that i had the 192s. they ski very short, especially if mounted forward of standard, but they are an incredibly fun ski. light, poppy, they ski switch well, slash well, rip big turns, cut short ones, and in general, just slay.
get the 192s
