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.
