I've been working on tying proper leaders onto braid. Using 50# power pro to 12# flourocast, 12# invisix, and 12 armor coated trilene.

The knot I have been using is the albright, done slow and well lubricated.

To test the knots I have a small scale to test breaking strength. Out of the 3 types of leader it looks like the trilene holds up the best, but even the best, the leader is snapping at the knot of just above it. Usually at about 8# pulling force. The scale is probably not accurate but I know the trilene is better at this point.

Any suggestions to improve the strength?

Actually, for the heck of it, I grabbed a piece of the flouro I am using and I pulled on it the same way as previously described. It's pulling only slightly more poundage before breaking so the scale I am using is very inaccurate and my knot is probably fine.

The Alberto knot is the best knot for connecting braid to fc, or mono. I have yet to break a leader at the knot using this method.

I suggest trying the Stren knot. It's what I use, exclusively.

Not that I tie leader to line that often but the alberto is about as good as I've found. Never is an absolute word, so it isn't in my vocabulary, I'd say rarely do I ever get knot failure with any kind of knot I use. I'll add line to a spool for freshwater and inshore fishing, but not to an offshore reel. That said I needed about 100yds of line and I didn't purchase a new spool. I added 30# to the 30# mono on my reel with an alberto, could not have been stronger or more solid.
