I'm looking for a source for the small line tighteners. The item I'm looking for is either plastic or aluminum, about an inch long, maybe 1/16th thick with two or three holes; the ones I've seen have rounded ends. The larger ones (2 inches or soi) seem to be readily available anywhere, but the little ones are proving elusive. I've tried REI, EMS, MEC, Wally's, Campmor, Canadian Tire, Gander Mountain and Seattle Fabrics. Most of them carried the larger one, but no luck on the small one. Need something that will work with line the size of Triptease or smaller. Any ideas?
