I really like the GSX platform. More stability and just as fun. I had a 1996 SPI and it was dang easy to roll that ski over at slow speed. I never did but had some close calls for sure. Riding the GS was much more stable. Just have to remember that on all skis, keep your weight to the center. Personally if a ski is a 2-seater that means ONE rider and a 3-seater that means TWO riders. LOL I don't ride double anyway. Who wants to ride on the back where you can't grip it and rip it? Have fun !!
