Hi, I've got a fish with a very foiled out deep swallow tail, which makes for fragile edges. The leash plug is in the middle at the top of the butt crack. I need a leash with a longer rail saver to stop the leash/swivel dinging the tail in bigger surf. I have an old FCS leash that did the trick but don't trust it any more. My other leashes can just about be made to fit, but not quite good enough. Any ideas?
