Nick Evans: If you don't mind me asking, what knot do you use bud? Anything that can hold down those monst fish of yours will do me just fine haha. The blood knot hasn't let me down yet but I've only used in on heavier line a handful of times.
When connecting your mainline to your leader I usually use a uni to uni knot, the problem with this is that it only works with lighter fluorocarbon (10lb-50lb). The blood knot is decent for fluorocarbon but with anything higher than 60 lb I suggest you use a swivel to tie to, otherwise the knot could slip. Even when using 30lb-50lb I always tighten my knots with plyers and make sure it is wet before tightening. When joining the swivel to the fluorocarbon I usually use a leader loop knot or a Lee Knot. The leader loop knot creates a loop which allows for a little more freedom on the swivel or snap. The Lee knot is snug to the snap or swivel.
Hope this helps
Good luck!
