I've purchased all my arctic fox tail pieces form Waters West in WA state, best dyed, best quality, reasonably priced. And, I'm not a tier/spokesman for them. Here's the link:]

You have to leave a lot of room for the rabbit/collar/head on the D&D. I use crosscut rabbit. I also use longer hooks, TMC 5263. Haven't tied any this year on the jig hooks yet. It's hard to get all the stuff on the front hook--flash, palmer chenille, rattle, flanks, flash, rabbit....then the deer hair.
Nice olive color scheme on the D&D. Had a nice brown charge a white/grey/silver combo last Sunday, He just butted the streamer and left. Had another flash the same pattern thru a riffle. That was it for the streamer action. Landed some decent 'bows and browns on various nymphs. Decent day. Glad some rain is coming.
