[VFB] Line question

[Ken, Carolyn, Alex and Hershel]

Here's a question for you.   I recently bought an Airflo multi-tip line and I've attached the loop to loop connectors -- you know the type with the little shink tubes.   However, I want to wind them with something to make sure they are secure.   What should I use? I've got some black 3/0 monocord -- I think it would work -- or someone told me they use fine diameter monofilament -- or ordinary tying thread? I wouldn't think color would matter if it is used at the hinge between the line and the sink tip?   Any suggestions?   Thanks   Ken MacGillivray Vancouver
