What are typical wind and sea conditions where you sail? The N20 should kill in light-medium winds, but maybe if the winds were on the heavy side, the F16 might sneak away because they won't have to depower as much...
Wonder how much that wing mast weighs? Wonder if it's as strong and "dope resistant" as the carbon mast...
If it is a wing mast, did they reduce the size of the mainsail to ensure the total sail area for the main is the same as the Carbon mast version?
