Too much wing air resistance. I can use a "pocket water" taper (6ft 4x) to make the cast but the wings spin the leader badly. Tied another version using poly wings tied very sparsely. Worked much better.
I think perhaps it's the double wing shaped like an X that's the problem. I didn't expect all the trouble I had since I've used single foam wings of fair size on spinners such as Green Drakes. Not saying there isn't "spin" but at least I can cast.
