I would recommend these. The Christmas tinsel streamer. These ones are pretty decent sized, roughly 6" to the end of the tail. Remember that pike will eat prey that is up to 30% of their body length so don't be afraid to throw a really big fly. I think the hook on these are 3/0 (I think) aberdeen style. They are almost 2 inches long. If I were going to tie any larger I would use a stinger attached with steel wire. Also, the epoxy head is really helpful to add to the lifespan of almost any pike fly.
