Was bumping this thread in connection with @Joeprunc 's question of is a new ski going to get him further. After re-reading this, I think I will go plus or minus with @6balls 's rule of 5 seasons. I just got my new ARC this year. My season is probably around as long as his, though I may get fewer sets. Hoping to change that. So, unless something comes along that is really going to help me in my progression, I don't think I need to change out for a few years, up to 5 or so. The size is good for me, the set up seems to work for me really well, and like all D3's, it is built beautifully. So should last a while. Thoughts anyone?
(Although I do want to get something wide to keep in the boat, like a Katana or something, to play around on when the open water is not perfect, and maybe even for beginning course skiing practice. My son could use it, and I bet it wouldn't hurt me to practice with it at really slow speeds in the course to learn lines, etc.)
