The ultimate fly to deal with 'short takes'! Lol!
But on a serious note, I tie my bugs with a hackle that starts at the head and wraps back to the tail for 2 reasons... The first and most important is durability ... Putting it on this way allows for 2 full wraps of thread over the feather versus 1 or sometimes NONE with the tail to head method.. Simply put, the way I use makes a more durable fly and that can't be debated. The second reason is because I prefer the look which is obviously subjective.. Each tyer will prefer one look over the other, I doubt either way makes a difference to the fish, just remember MY way makes a more durable fly =D
A couple examples:
