Honestly, I don't think you'll hook up any less using heavier fluorocarbon leader. It is nearly invisible in the water. Granted, I usually fish from a boat, and in strong current, so have switched permanently to Rio's F+ in 2x. I have to bend a rod pretty good to get a healthy sized cutt to the net while anchored in a 2 knot current, and I hate to leave anything stuck in the face when I break one off. I'm generally using a tube fly, so all they are left wearing is a tinned, light wire hook. With the 12 # leader though, I can catch and release a dozen or more fish and never give a second thought to using the same fly and knot all day. I can't remember breaking one off in the last couple of years. They come unhooked, but almost never break the tippet.
