NEXT2NUN, NO , I do use it, an spey hackle also, but being a cheep Bastard

 an learned  trick from other tyers, that's GOOSE
do a search on BURNING FEATHERS. not to say you have to use GOOSE, it is stiffer an will hold shape, but still flutter, the RHEA an SPEY HACKLE are more flowing all depends on what YOU LIKE. INTRUDERS

 got a list of them to do 

MERRY CHRISTMAS, GOOD LUCK GOOD TYIN
