The millenium marine seats are very comfortable. The sidekick is well made and is adjustable in all directions. It should almost fit any boat I would think. It is easily moved front to back. I have the same setup with extra bases in the back. I actually keep it disassembled in the boat so I can switch to spider rigging at any time. Only complaint is that with all the connections and adjustments is that it does have a little wobble to it. The base has 3 legs and IMO they should be a little longer. I don't have any input on other brands because this is my first double seat setup. I just looked at a new 2070. I thought they had the 3 across pedestals on the bow from the factory.
