Hey painter, When I tie my own walleye harness, I use 17 # line. When i tie snell knots I use 7 wraps per hook. I dont think that it matters how many wraps you use. 7 wraps seem to work for me. When I put floats on I use 3-4 floats and still use a spinner blade too. Usually a #2 colarado blade and it still floats. I usually use #3,#4,#5 colarado blades. As far as how many beads to put on a harness is all up to you. I have seen 3 beads up to 8-9 beads on a harness.
