Truly ingenious system for being able to thread either loop and go or 6-to-1 for all sails. The only question to answer is whether the cleat position makes it easily compatible with a rig winch like that made by Chinook. I hate to sit down to rig. Duotone's other product XT extension is only truly fast for loop and go with pulleys in the straight orientation, all other situations I find it slower to thread, particularly that last long hole. Rig winch is faster and more precise with less effort than the XT, but I find that with certain extensions the last cleat orientation is not ideal.
