I rarely troll, but when I do ... and use RR's ... I use only one at a time, per rod ... and only one rod at a time, in hand. Mostly I use this method as a "search" method, and all I'm trying to do is cover a section of bank, usually at a certain depth contour, just trying to find spawning beds or isolated spots of cover. Otherwise, I'm casting the RR's
I've done better casting them, than trolling them, and rarely lose one when I cast them. I use the 1/16oz marabou solid chartreuse, and trim the tail feathers ... cutting them off about halfway between the tip of the feathers and the hook bend. I feel that this accomplishes two things : keeps the "nippers" down to a minimum - stops the feathers from tangling in the swivel, during the cast. The small, stubby profile of this "trimmed" bait is no detriment to the number of strikes ... and I usually don't lose a fish, once hooked, since they are mostly hooked in the roof of the mouth.
If you haven't already seen it, check the post about Cabela's sale on RR's !! Locally, off the shelf price is $3.00/2pk. Just a few months ago, they were selling at $2.50/2pk.
