I tie mine with a gold or black bead, and add a bit of green ice dubbing
just behind the bead. No other weight is used. I use #12 and#14 2X long
hooks. The couple beadless weenies I've tied produced zero results. I've also
tried red weenies with zero results.
I simply cast them to a likely-looking spot, wait a few seconds (I often
get an immediate strike), and then give it a few
small twitches. If nothing
strikes, I'll retrieve a little line and repeat the procedure. I'm not much of
a nymph fisherman, and I don't use an indicator. The other day, I was
fishing a stream where I was forced to roll cast. I was using a green weenie,
and several of my roll casts felt like snags, but they turned out to be fish
