I have a few spots that I fish in small rivers that are a very fast deep troughs of water. This section gets very narrow, very fast and I think gets to about 10 feet deep. It is loaded with fish and I would like to get down to them (if possible). The section just above this very fast and deep water is not such that I can cast up in to and hope that I get my flies down before they hit the fast, deep water. It is a short fast deep run and I would love to get my flies near the bottom. I am fishing a floater on a 5 wt with a couple of nymphs - one of which is tungsten weighted. I have tried split shot and maybe I just need a bunch more but am wondering if this forum brain trust has any additional ideas. Could I use a weighted line in this instance? Would a weighted leader help? If more split shot is recommended could you tell me how much and how many feet between weight and flies? Thanks in advance for any ideas.
