Heres a cool product I found on a German fly shop web site. These are not for the dry fly guys and some folks may cringe, but these seem to be a neat product nonetheless.
Heres a description from the website:
Unique, pre-formed body nymph from a combination of plastic and tungsten.
A great product, complete with brains, a strong chest and a segmented body.Can be easily integrated with three-thread or with a thin Dubbingstrang on the hook shank.The high dead weight, the use of lead wire or beads unnecessary.This body can be colored with waterproof markers or colored lacquer.Available in 8 sizes.
Mylar piping comes in a few external colors and a couple of different cores that the mylar is braided around. Most are braided around a tan to brownish twine and some are braided around a zlon like material. When i find the piping braided around the zlon like material, I buy that one vs the twine material.
You can use the mylar braid for its intended use, bait fish bodies or unbraid it for tinsel or body material. Some chironimid patters use one strand of tinsel for a trailing shuck.
You can use the zlon like strands for spent wings, parachute posts, trailing shucks, chop it up and put it in dubbing, breather filaments for midges and buzzers etc etc etc. Experiment, I'm sure theres more uses out there.
