I make and use Furled Leaders for all my fly fishing whether it be warm water or cold and my Furled Leaders have a Shorb Loop built-in both ends and I use a loop-to-loop connection for attaching the Furled Leader to the end of the fly line and a loop-to-loop for attaching the tippet to the tippet end of the Furled Leader and have had no problems. I usually start out with 5 to 6 feet of 6 pound test fluorocarbon for tippet and will use a double surgeons knot to attach around 3 feet of 4 pound test fluorocarbon to the end of the 6 pound test tippet for the smaller flies. My opinion is you should have no problems with using the loop-to-loop system.
