How to connect braided line to fly line properly?

[Bender]

Can sameone help me to find a good method to connect braided lines like Power Pro to flyline? I need a good knot to assure me a non slippage from Gel spun and to avoid cutts on the flyline; this due to the thinner diameter of the G.spun or braided lines.
Many anglers(like Max Garth and Peter Morse) suggest to form a loop on the G.spun with the bimini twist (70 turns) than using the Gudebrod with coaxial loop and put the loop formed on the g.spun in to it; this to prevent cutts on the fly line.After that a loop to loop connection to joint the backing and the line.

I agree with that method 100%.

It also allows you to switch flylines easily

A 70 turn bimini? The standard was 20 to 40 and now some people are using 12 0r 15 turns tested with equal strength and durability. It can't be that much different connecting to a flyline. I'm no expert when it comes to fly fishing but im assuming the braid is the backing and that loop to loop connection may never sail through the guides.

a good Doug Olander article from S-F August-06 issue about braid to mono knots ..he mentions the 12 turn bimini as the best to use after testing rather than the once used 20+ or more bimini

OK captcl ,but the problem with gelspun backing like power pro or bionic braid is its thinner diameter that can cut the flyline when on heavy pressure(like a big fish on the reel like tarpon ),so to avoid this problem many people suggests to use gudebrod on the loop formed in the gelspun and than connect to the flyline loop.
For the turns in the bimini with gelspun i don't know,but i usually use 20 turns with standard backing and then i put Pliobond on it to protect itself from cuts and slippage.
