L.D. Marine Products: Swiveling Rod Holders & More
I've got these on my boat (plus standard Lee type for my bass rods)
Long bent butts & long holders for big fish!
I wouldn't suggest the golf ball thing unless your either into smaller fish or want problems if your on a bigger fish.
Last time I was in R&R they had 1 CJ holder on the shelf so I know they can get them.
