Just finished these up this morning, I originally just laid them down the sides (reels to the front) and used the rubber cords to hold them in place. Worked good and never an issue of losing one BUT by the time I'd get to where I was going the tips would be so mangled it would take 30 minutes getting them untangled in order to fish.
I wanted something easily removable and came up with this idea using some dovetail bases, I may add another in the center to help support the rods and make them functionable for shorter rods. The center rods are Pinnacle to which I am not very pleased with and will be replaced, 16 rod capacity.
