i've seen guys search for 30 minutes or more for a stick or misplaced toggle to finish out a marlin spike. i've used'em myself. but here's what i can't figure.
why? especially if you've got caribiners or a ring handy, or just a knot in the webbing or rope itself. if you've got room for a spike you likely have room for a loop.
i'm sure i'm missing something here but i'm not certain what it is.
