Used garden hackle for years up there bottom drifting for Steel. Seemed to me that they fished pools better than swinging fast waters. Slower delivery was always my guess.
That said working them behind rocks and jams in faster waters did very well too. Still use them often.
Never had all that much luck using them under a float but some guys do well that way.
Bottom drifting a pool a year or so ago with them and got nothing-moved out so the guy behind me could get a chance -he hit a dropback first cast drifting a bobber with a crawler lol.
