Thanks for all the input, yes the advantage seat is of desire and I guess wanting to look new, believe me I've added everything possible to my proangler I can think of, from the seadek flooring, LED lights, micro power pole, hobie livewell, well I think I'm getting overboard. The simple solution of the wooden risers, do you feel less stable leaning from side to side, bc of the higher center of gravity?
My curiosity was up so I checked to see if the Vantage seat would even fit in the seat area of the 2012. It does, but the fit is close on the ends of the front legs as far as fitting inside the raised sides. I suppose it would be possible to add those 2 black retainer mounts so the front Vantage seat legs would hook into them. That would require the right screws and decent sized washers on the back side.
Again...looking at it, it would be a snug install and might require the front legs to be inserted into those front retainer bases with a little side pressure. The seat doesn't sit too bad without the rear being raised, but it probably would not be too hard to add something to raise the seat up slightly in the back to simulate the "Vantage" position. Then you would just mount the retaining strap like the 2013 model.
Not saying it "not" doable. I'm happy with the older seat on my 2012 for now.
