@HighAltitude, I am about your height and weight, a little older and female. My max speed is 32. I bought a 66" Vapor Graphite last summer and thought it was every bit as forgiving as my old D3 Z7 ST. I was told the Graphite would be more forgiving than the Lithium or Pro Build. Some people were telling me to get a Senate, but I was in between sizes. I didn't want to go up to a 67" since I always had to do a lot of fin tweeking on a 67". I thought going down in length we negate the extra width. You should demo a D3, they are very forgiving skies without giving up any performance. In fact 2 of my old D3 skis still live at our lake. Both people instantly started skiing better on them.
Where do you ski in Colorado? We were looking to move there about 4 years ago, and might start looking again.
