I fished them on full floater or int head and slow sink tip. Always single hooks, fished 60 - 45deg
Only one way for me, fast and super fast strips.
I find i never (or extremely rarely) miss a salmon take as when they want them, they have them. I assume this is due to the speed i am retrieving and not giving them a chance to think about it. Trout are more likely to come up short or pluck. If so, i cut back the hairwing a little or go smaller. I find i only ever catch belters of trout with them, 1lb class and above, never under. They cover options for salmon, sea & browns.
My most successful pattern for trout or salmon without doubt, regardless of water height or temparature. I fish them from Feb to Oct. Standard black and white in 2- 6inch (inc wing).
