Nice article. I think that we've seen that one and its siblings before.
Karen: Crossing paths is the interesting thing about turns 11-13 at CMP. There really isn't a single line. I choose mine based on the rider(s) in front of me and what i'm trying to accomplish. It is extremely useful to understand what each line accomplishes and how to execute them.
Matt: When you think about turns 1-3, think about where you make time in each. Then the line become obvious. the catches are that 1) someone inevcitably is on your line for at least part of it, and 2) it is a highly visual part of the course. If you're looking in the wrong place at the wrong time, the game is over. Most of the benefit in 1 is carrying speed down the straight, so on the brakes. 2&3 are all about picking up speed for the straight between 3 & 4...so back into the thinking from 5 or four and plan it out in your head.
