We have had North for several years now-and the main is quite different from other sailmakers (Ullman and Quantum) that I have used in the past. As wind decreases, rig wants to be uppers tighter than lowers-I go around 1000 uppers 750 lowers for the light stuff. This puts more prebend in the rig. Sets up really nicely, with a deep, smooth draft. For heavy air, uppers and lowers the same, around 41-42 on the loos.
