I'm considering purchasing a used pair of Vector Heavy Metal downriggers with 4' booms, swivel bases and 3 rod holders per rigger. Both are mounted on an 8' aluminum bar, included with the riggers. This setup would be mounted on the back of a Lund Tyee 1850. I'm new at this and am working on getting the boat setup for the big pond in 2012. I'd appreciate feedback from owners or users of the Vector Heavy Metal rigger as to how well they worked and if you had any problems. Thanks, Mark
