Good advice so far Terry,
get yourself some flat and embossed gold tinsel. It's metal and won't slip about like your silver holographic will and will resist the trout teeth better. Also in spite of shuckraiders preference I find it more effective than oval tinsel or wire. Robust enough to resist a bit of velcro and dubbing needle action too to get that all important scruffiness.
For the tails try to use just the well marked guard hairs (better from a body patch than the ears) not the shorter under fur as well. A toothbrush is a handy tool for clearing out the bulk as you hold the tips
Try some tungsten beaded versions in various colours and you won't have to worry about crowding the eye and more importantly they'll get down where the fish are quicker when necessary.
Keep 'em coming!
