Several times last year I tried a 12 foot floating tip with about a 10 foot leader attached to the end of my Skagit head for floating line work. Didn't like the way it turned over, but it was a vast improvement over my mid belly when the wind was blowing.
This year I put a floating poly of about 10 feet with 4 feet of strait tippet looped to the end. The poly was olive colored, so I figured there was no fear of scaring fish with it so I went with the short piece of tippet. It turned over great and the fish came to my flies with reckless abandon even in very clear and slow lies. I was surprised how well it worked. I hadn't used poly leaders in 8 years or so, but I'm sold on them again, at least for conditions that don't require getting down with real heavy stuff.
