Single Articulated Buford - Yellow/Red/Black 8-9"
Tied on a single 5/0 Gamakatsu B10S hook with a 40mm stainless steel shank in front. This is an average to heavy dressed version. Tied on the sparse side to be mostly neutrally bouyant, while still allowing a slow sink rate and avoid "prairie dogging".
Coming in at 8-9 inches you can easily cast this fly on a 10wt and up with a sinking or intermediate line. A great upgrade from the single buford to add a bit more length and action.
