i've used a fly line connector made by eagle claw, i can't remember the exact name, but do know they are used for connecting fly lines together (i think), they look like a little barrell with an opening at each end and a little slit in the middle. they work great, you can real them up through the guides in your pole even. If i can remember the name i'll post it. In the mean time check out teh fly isle at your local sporting goods store.
