They call it a Fluor Red head ... but, it looks more towards a flat orange to me. That picture I posted is from their website, and shows the tail to be more yellowish chartreuse, but the ones in my group are more towards the limetreuse coloration.
My original thought when I first saw them .... Christmas jig !!
I've caught many a Crappie trolling a marabou RR behind the boat in the Spring, usually when my next target area is too close to bother starting up the big motor and idling to it. I couldn't even tell you how many Crappie I've caught casting or trolling a RR. And so far, a solid Pink or solid Chartreuse marabou RR has accounted for over 90% of those fish. And I've done so well with the solid Pink that a couple of my fishing buddies have either received some of them from my stash, or saw that they did so well that they've ordered their own from you !!
