My tolerance for increasing costs on tying materials is apparently infinite. Once I find something I like that doesn't have a lot of great alternatives, I'll apparently pay anything. I suppose I'll go broke at some point, and that should slow me down.
It's even worse for gear fishing these days. Lead is priced like gold, and a 5-pack of the Mini-Sardine Yamashita hoochies goes for $11-12. Yes, that's over $2 per squid. I jump on chances to buy cheaper alternatives, but for some reason, most don't seem to work as well in my lures.
For the tungsten jig thing... I have become addicted to slotted tungsten beads for dropper nymphs and mini leeches, but wow, they are pricey! I also like tungsten putty for leader applications, but it can get messy and would probably cause more problems than it solves in a hook shank application, but if you could find a way to apply and remove tungsten putty from the head of a hook shank without gumming up your fly or your tippet, you could get a lot of fishing time out of one of those pucks of putty. It could also be nice being able to adjust the amount of weight, which you can't do with beads.
