Nothing wrong with staying with a company that's always treated you right.
I would always consider buying another brand if they released something new.
I jumped ship form Arctic Cat back in 05 and never looked back.
The SXR is a better handling boat than superjet. I also think kawasaki SXR has better electrical system & pump set up than the sj. Yes, the SXR weights more but you don't have to reinforce or refoam. SXR will suit any rider but the guy that wants to just flatwater freestyle. I agree with you about using the right boat for the right purpose. But overall I think Green rules.
The yellow is the worst color ever for the SXR. Change that otherwise ride the crap out of it.
Good call on switching from AC. I like the drive shaft setup better, but the pump seal on the SJ is more idiot-proof IMO. I like the color..... on something other than that ski. I like the baby blue SXRs. I prefer my SJ for low to mid speed handling, but at speed the Kawi is pretty darn stable. Way better than anything else I've ridden at over 50
