Had a few 550's (back in the day) but still consider myself a beginner (newbie) I have just picked up a 90 super jet and a 80 js440 the 440 was funish for an hour but realized I needed a lot more power I played with it right up until it torpedoed a dock. Both skis need some love so I found the sight and will hang a hat here. Hoping to learn and develop my addiction !
