I will wade in here to save you time.
Thank you to all for your answers. There are some points I'd like to clarify:
ynot:
Never used pencil lead as a weight.
How is it better than removable 'winged' splitshot?
If is a strip, how do you attach it to the main line?
Pencil lead is usually attached to the line using a three way swivel and surgical tubing.
The advantage over split shot is that you can attach a large heavy piece that will get you down into deep pockets in fast currents in a way it would take 10 split shots.
What size of woolly bugger do you suggest and would it work for salmon?
I most commonly use a #6 or 8 wolly bugger and coho love them.
skaha:
Could you recommend a specific brand or example of a commercial fly floatant?
I use "Gink," it is a silicone based dry fly floatant.
Would using a wet fly on a 3' leader, swivel, splitshot and slip float constitute "fishing similar to chironomid"?
Yes, except that chironomid fishing is using done at a specific depth (usually 1 or 2 feet off the bottom or top of the weed bed), not using a slip float. The drop shot rig describe below would keep the fly up off the bottom.
Could you explain the "drop shot rig" in more detail; if the leader with a fly is attached a foot above the weight, how can you "reel in the fish without removing the weight"? (Perhaps you could include a link to a picture of this rig?)
There are a lot of images of this rig online:
A picture of "streamer type or minnow imitation fly's" would be much appreciated.
What length of floating low vis line would you recommend to attach to monofilament line to float a fly; would a dry fly float still be useful in this setup and can the floating line be attached with regular knots without a special device?
Really do not know what you are talking about here.
