I usually use a nail knot for this connection, but I'm wondering how many of you, if any, use some type of cement (Pliobond,etc..) on top of the nail knot? This question is basically for smaller 3 & 4 Wt. stuff, but share your opinions on all sizes if you care to. Ok, one last thing, I also use the perfection loop-to-perfection loop connection for my butt section to new leader junction, is this still common practice??
