-Hook
-thread
-lead weight(in the right place and amount)
-marabou(in the right amount and length)

It's easy once you know how but it isn't an easy first fly.
I would say it is a great LEARNING fly because it teaches you many techniques in one fly but it is not an easy first fly to tie.
Worms are MUCH easier!!
Good fishing technique trumps all.....wish I had it.
