I think you'll be much happier with the new Helm seat.
My biggest issues with the Helm seating on our 24, was it was uncomfortable for any long runs, and it was shoved behind the wheel. I'm 6'1", and felt stuck behind the wheel.
I think the one I bought, came from Cabelas also. Good quality, and a decent price as well.
I purchased arm rests for the stock seat, and when I changed it to the new cushy one, and shifted the seat over into the aisle, I added the second on the controls side. They bolted right on to the newer Cabelas seat.
