Setting up salt fly leaders

[dannyplug1]

I have a DVD by Chico Fernandez he talks about a 60 20 20% leader formula. I have tons of green berkley big game is it ok to use it as leader material or is it not stiff enough? If it is not stiff enough what type and brand do you guys use? Also in the DVD he used a short piece of leade 4 inch or so and attach the leader with a loop to loop connection what test do you use for this connection the same as the longer but part of the leader. Lastly l need a formula for an eight weight and ten weight fishing the surf for stripers. Thanks for working through my confusing post. Charlie
