My signature tippet leash was originally the best method to carry tippet on the early flask pack prototypes. I cant overstate how much easier it is to have your tippet spools horizontally oriented instead of vertically stacked. Its literally the difference between being ready and fishing on the water or fumbling on the bank, frustrated. Mickey Anderson SLC, Utah AKA: Fish Whisperer, FlyNinja, The Stick, Mick The Stick.
