We have 15ft Taco HD poles for our outriggers. For our center rigger we got a 12ft Taco center rigger, but put it in our center rocket launcher rod holder to get it as high of an angle as possible since we run a WWWWWWB line and wanted it above our long outrigger lines. Having it in the rocket launcher holder works great and we use the center rigger line to hold it in the rod holder. We also notched the bottom of the center rigger so that it would fit over the gimbal pin to prevent spinning. Works great as I said. The drop back in the line with this very steep angle really is not that bad, especially when you consider you have 200-400yds of line out already. If you are concerned about the high angle and the line drop-back, then use a tag line. I tried using a tag-line and it worked well, but then the line was not as high as I wanted to keep above our long outrigger lines. Every hit that we have had on the center rigger has resulted in a hook up except the couple of hoos that cut the mono/flouro leader.
The only thing I would do differently is that I would tried to get used 15-18ft outriggers and used one of them over the 12ft center rigger. As I said, I want it high as possible for the WWWWWWB line. So if anyone has a used, cheap 18ft black/gold outrigger for sale, let me know.
Hope this helps.
Good luck,
