I don't recall. May have been from an IronMan4x4 sale online? It is pretty common to need to pull folks out of mud/snow around here especially in the spring/winter, that's what I got it for. The F150 or Rav4 off in the ditch on the way to work....
For sure I can see the application for snow use on passes with that type of rope but personally haven't been into that kind of snow at SAS. I'm not trying to dissuade anyone from bringing specific recovery gear, just that there are specific applications and limitations to each piece of gear and the user should understand and follow them. I just have yet to see a recovery up there where I would have been comfortable with momentum and a kinetic rope. If I was putting together a gear list for someone new to the game, I wouldn't suggest a kinetic rope as their only strap. Too tempting to press it into service where it’s not appropriate. Nobody's going to get stranded in our groups, it's better to remain safely stuck and wait to get the right help/gear than to do something sketchy..
