Narrowing my choices for a new ski and boots this spring. The Radar choices are the vapor graphite or lithium. I will also be replacing my animals which need rebuilding. My typical set is a warm up back to back 15's, 22, 28, and a couple goes at 32. On my best days I run 32 and am very happy. I'll be 55 this summer and have learned to enjoy a nice clean set rather than push far beyond my capabilities. I also enjoy a 3 or 4 mile free ski a few times per year. In all I'm happy with 20 to 30 sets per season. Questions - graphite or lithium? - profile or vapor?
