I use a 25 turn Albright for Mono to Spectra.
-Its a Squidco favorite and those guys
tie a lot of top shot knots.
You could imagine the internet outcry if it was a bad connection, or that knot was failing.
Its easy to tie and see if the knot is dressed correctly, as the coils will line up cleanly next to another.
I have not had one fail.
------------------------------
I never use a Palomar Knot, unless I want the Hook to break off in the event I snag kelp. The same goes for the Dropper Loop knot. The D-Loop works good if you hook a BSB and want - a break-off, but you will leave him with a hook.
-It works for yellowtail, but I still don't like it.
I would rather use a double surgeon, or triple surgeon knot, or a 3 way swivel with SD jam knots at the connections.
I always use the San Diego Jam Knot for everything, including a straight Spectra connection.
15 turns on 65-80 straight spectra holds without slippage to a hook, or swivel.
On Mono I use a 5 turn on 30 or 40 lb test.
You can also use a double SD Jam Knot in Spectra for a larger knot, or large fish (bigger that our YT)
