Spend a few minutes tying a few of these up and fish them, I will bet after the first strike you will be as addicted to Ska-opper fishing as we are, and yes for those of you wondering I am going to give these flies a shot over some trout as well as Stripers this fall.
Hook; TMC 8089, TMC 811S, or Mustad 3366
Tail; Marabou blood quill tied over a few strands of Krystal flash
Body; Estaz or Cactus chenille
Top; 2mm foam or 1/8" Evazote
For Smallmouth I seem to prefer the brown / root beer color combo, but have caught fish on white / pearl, yellow / yellow and black. A size 10 8089 (currently on back order) or a #2 3366 hook fit in well with the Smallmouth, but hook size can be adjusted accordingly.
As a added tip try hanging a small Nymph or Crayfish off of the bend of the Ska-opper. The popping will get their attention and when they see the dropper they may be more inclined to bite it. We call this the "Dinner Bell" set up.
Enjoy...
