Jason,
Here is what you are looking for:

I have made and used the above and now only use the short (6-8") mono nail knotted on the end of my fly line with a Perfection Loop at the other end to do a loop-to-loop connection for my furled leader.
Both will work just fine. You determine which you like the best for you.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
