The best connection I have found for fluro to spectra (without using a swivel)
is the Tony Pena Knot / also called the Bob Sands Knot.
Tie a double overhand knot in the fluro
Wrap the spectra 12 times up and then 12 times back down crossing over itself
(creating X's as you wrap)
Wet the knot and draw it in one continuous motion.
---------------------------
It casts through the guides nicely and its very strong.
