rodney, the knot i tie i have used since the late 60's. it is tied like what they now call a uni-knot, but i double my line. with smaller diameter lines, you need to use more wraps. 20lb. mono, i use six, 40lb. braid, 8, and 20lb. braid 10 wraps. 4lb mono 8 wraps. chinching down the knot is also crucial. cinch down main line and single tag end. do not pull up on the tag end that is a loop. it would be a rarity if this knot ever breaks in the knot. you can loose lots of line on break offs because the line breaks somewhere up the line and not in the knot. can get expensive with braid. but, i want to know that the line is the weakest link and not the knot.Oldfart9999 said:Bo, pray tell what is the knot? Flouro is heavier than mono which can be an advantage, it has a bit less stretch than mono, it is almost invisible under water. The biggest problems that it doesn't recover from stretch like mono, second would be that you have to be very careful tying your knots. Flouro is a bit harder than mono so it doesn't cast quite as easy but the manufacturers have made great strides in castability and it works well enough for deep cranks where every extra foot of distance is an advantage.
