There have been times I've been flishing freestone streams and encounter deep pools and wish I had a way to fish deeper. I've tried adding weight but it doesn't seem to get down quick enough or deep enough before the current sweeps it away. So I bought a sink tip kit with 12 feet of 9 in per sec line. I was thinking about making 2, 4 and 6 foot sections with loops on each end. Any suggestions on leader formulas using these sections on 5wt line? Should the sink tip section attach directly to the fly line or should I use a section of heavy monofilament?
