I have a 6.5m boat with hardtop so going to run a wishbone style base on the side of the cabin. Looks like the 2 main contenders are Kilwell or OceanBlue in my price range. Leaning toward the Kilwell as it looks to have a more robust locking mechanism and cleaner installation. 

I'm not leaning one way or another on fiberglass vs carbon but trying to keep costs down where I can. 

Where I'm getting a bit confused is around the pole configurations. Some of the outrigger poles seem to be much thicker overall and have a smaller diameter shank that fits the 42mm bases. Others are thinner and the shank is either the same size or even wider than the base tube. Then add in 1 piece, 2 piece, or telescopic and who knows how many other options. 

Would anyone have any recommendations on which direction to go? Currently looking at the Kilwell ST12K however that seems to be a 1 piece and not sure how much of a pain that will be on a trailer boat. 

Ended up going with Killwel long reach bases. These have a much more substantial mounting pattern than the wishbones and spread the load well. They are also easy to configure, use, and strong enough that I can go with longer poles if I want to. 

I chose the 4.6m Killwel long reach fiberglass poles. They seem plenty stiff and being one piece no worrisome joints. Due to stock issues I ordered poles that needed to have the guides added. To future proof myself a bit I went ahead and assumed that I would be adding in the 1.2m Killwel pole extensions at a later date, I started my first guide in a place that allows me to mirror that in an extension and have a consistent spacing all the way up. Bascially 600mm from the base so if I do add the extension, I'll start that one at 600mm and then have the same 1.2m spacing between all guides.

This setup did cost a bit more than a wishbone kit but will allow me to confidently run 6+ metre poles in the future with no worries of having to replace bases or rip out of the aluminium hull sides. Overall very happy with the set up and glad that I spent the extra little bit to have a robust set up that's easy to deploy from the deck and plenty strong to go the miles. 

Out2sea, I think you will find you will have more success talking to a more specialist company (Bonze, OceanBlue, Douglass or myself) to get a better understanding of the pros and cons of each option. It is a bit overwhelming with the amount of combinations available in the market. Im sure all of us would happily listen to your needs and tailor fit a solution for you.
