RE: North Sails "One mast fits all" concept.
Roger, no, the best mast according to North for example the ICE is 400 for 4.7 5.3 and 5.7. Only for the 6.2 they recommend the 430 over the 400 + CX. I??m 90 kg been windsurfing since -89 and the performance of the ICE with a 400 is just amazing. I also ride an 8.3 daytona with 460 + CX and it??s great.
