I put some Loons knot sense on usually, mainly because I keep snagging the fly on my nail knots with tailing loops and other generally poor casting techniques, and this seems to help. It also helps run through the runners for a quick cast if sight fishing.

My point is though that after reading several reviews I have learned that these products, from superglue to specialty knot products, make no difference to knot strength at all, merely smooth the profile.
