Now Art, you're gonna get me confused or maybe get the fish confused. With a riffle hitch maybe the line doesn't come precisely out of the middle of the hook eye... cool

I've never used a riffle hitch but should have a few times. One mid September after a morning hunting deer, a friend and I unlimbered our fly rods and hit a large brawling creek. More rainbows in bigger sizes than most creeks, lots of 10-12 inchers. I tied on a variation of a Yellow Sally, with some gold rib on a grey skinny body and some grey hackle in the yellow. Those fish liked the fly to skitter over/in the surface, swinging in an arc with a tight line on quartering casts downstream. My biggest of the day was back under a log facing upstream where the big log made a dam across the creek. He would wait till the bug or fly was just about to go over the lip of the little falls and then shoot up, grab it and go back down under his log. I saw him take a bug so drifted my fly through but he didn't take till I tried again and skittered the half wet fly across the current. Drag? What is drag?
