The problem is no matter what I do...the braid just behind the connection knot will get frayed. It could be within the first few casts of the day, or after a couple hundred casts, but sooner or later I can feel/hear the THUNK of the knot catching in the guide train and the braid will start to separate behind the knot. The floro leader and the knot itself would not be damaged in any way.
I'm using YGK Upgrade x8 14lb (that's like 4lb "normal" braid dia) to 6lb Sniper. Tried both FG and Alberto. My knots are perfect. No matter what I do, if the knot is inside the spinning reel spool this happens. I've resorted to a 13ft leader just to keep the knot outside the spool, but then I'm casting with a 6-7ft drop. Knot outside the spool zero issues.
Any suggestions?
