blue holographic tinsel by UTC ,Veevus . I have caught plenty of trout on all colors.I did really well on red last Saturday with a 9 foot flourocarbon furled leader I twisted up my self used a # 5 tiny split shot 12 inches from the fly. Bennett blue is really just blue tinsel by Utc. Brown hackle countered wrapped with small copper wire through the hackle and over the tinsel.
