streamers are a huge pain in the ass and every time i'm standing around stuffing them up my pant legs i get called a kook by dudes who look like they spend way too much time on tgr.
still, i'd much rather look like a dork than lose another ski, and they do work well. these days i just carry a roll of $5 neon flagging tape in my back pack. if it's deep and i'm gonna be sending it i just rip off a few feet, tie it to my binding, and i'm good to go.
