Joe,
I'm not Tom, but I've been using his method for twelve years or so. In fact I have a full-sink line on a reel that has the first super-glue connection I ever did, and that connection and line are still going strong after all that time. On my leader, I use a small loop-to-loop connection where the tippet hooks, and the leader remains the same length, and as I've stated, the line to leader connection has never been changed. I've never had a glue connection failure, on all the lines that I've used it. Tying leader on with a nail knot takes more of your line, when you replace a leader, than the glue-knot. The only drawback I've found, is that it's more labor intensive to glue, than to knot, when you're on the stream.
They're just fish, right? Right?
