You folks have given me plenty to think about, and for once, I don't have to buy any new gear, which is some kind of a record, although I could use another five weight fly line so I could have a dedicated chironomid rod such as Zen has.
Zen, your comments about the toothpick problem with Corkies got me to thinking. There is a product called a Peg It made for pegging worm weights used for bass fishing. It's a soft yet tough plastic that is tapered and resembles a nail. You thread the sinker on your line, put in the Peg It, pull it tight and clip off the excess. The sinker can then be positioned just about anywhere on the line. I think this might be the answer to pegging Corkies if the center hole is large enough.
Another option is to use another pegging technique used for Mojo sinkers. Here a tool like a bobbin threader is inserted into the hole (once the weight or Corky is on the line) and then the threader is used to pull strands of rubber into and through the hole. Once again you clip off the surplus.
Since there is no weight, virtually, on a chironomid rig, it seems this might work well.
I would try it this weekend, but the elusive blackmouth calls. Next week, between assignments, I'll head out to Gibbs or maybe Leland if I'm feeling lazy, and give it a whack.
Thanks again for the good advice.
