I've used wire, bands, and thread and it depends what I want to accomplish. When it comes to spinnerbaits I'll either wire tie or I use bands, with the bands I can carry a few heads and 2 dozen skirts in a small space but wire tying when space isn't a problem. Jigs are a little different, if I need something quick before a trip I'll use a band but most of the time I use thread or wire. If a jig has a weed guard and I'm tying with thread, then the weed guard goes on after I'm done tying, if I'm wire tying the skirt, well I can do it with the guard in place but it is easier to do so without it. When it comes to hair, fur, and feathers, then it is only thread, Danville 210 denier flat waxed nylon thread to be exact.
