But I've also heard people say that Icarex doesnt strech appreciably so the degradation isn't a problem?
Also as we know the trubulence caused by an uneven surface removes energy from another area such as drive or lift.
I've not a had a lot of time on a pro so wanted to know.
The classic sail seamed to work OK
Of course we do not have access to the testing processes either. I like the JB sails and the initial JB Pro sails but do not have the means to test the relative dynamics objectively.
The last set of 1.5 JMH sails with the random graphic (think Kites on Ice) which are slightly older than the last set of 1 JMH sails (10 years) are unbelievably soft now. It might be interesting to set up some means of comparison... <grins>
('trubulence' and 'seamed' appear to be appropriate if only phonetically)
