I am trying to decide whether to buy a new ski and if so which one. I've been on a 9500 for about 7 years. I've researched skis until I don't know where else to look. My question is would I notice a significant difference by changing skis. I've been looking at a Strada, X7 ST, and a Senate C. I read somewhere that someone had a Senate C and it was a little slower than his old 9500. I haven't skied on a course in about 7 years but I ordered one today from Ed at EZ. I currently ski 34 mph, weigh 200, and skiing on a 67 200amp 9500. Any input would be greatly appreciated!
