Do you have a "go to" productive Speck fly that has proven itself over the years/decades? Care to share?
Mine is a fly I invented/refined after a mix of experiences that led me to create this pattern. I call it the "ScuCraLee".
It is a somewhat complex fly to tie but worth the effort if you are focused on big Specks. It can be fished to simulate either a sculpin, crayfish, or leech. See my video if you want to give it a try.
