That's solid! I'm running 5 right now but the GS skis and powder boards (also 115 underfoot) rarely get used. My SL skis and all mountain skis (Line Supernatural, 86 underfoot) are good early/mid season and then I have my touring skis (4FRNT Raven, 104 underfoot, full rocker, 29 m radius)....so they're slightly flawed but ski a lot more reasonably than the #s suggest. Next year I'm looking to maybe ditch the pow boards and GS skis for another touring setup, something mid 90s and with a bit of camber to push into.
Sorry if OT, but this thread and the ski thread sometimes seem like one in the same
