Got a reply from NP directly and it seems everything I tried makes sense to them and they are still bamboozled.
It was suggested to try a new SPX or TPX mast rather than my older X6 and X9 .
This wont be easy.
Im also confused , I am led to be believed that all NP masts have the same curve , ( for ever ) , and the upper and lower carbon as well as the years all supposedly have the same curve . It says so in their brochures .
The masts I use work great on all other NP sails I have and have had.
So what gives ???
Either 1, the new masts have a different curve .
2 , im a chopper and im missing something , ( high probability )

or 3 , there is a problem .
Not that its a big problem but I did notice the other day way overpowered that the cam did not lock and it was moving. I couldn't tell the difference when it locked and when it didn't apart from the visuals I was getting.
Ill go hee for tiggy if they admit there is a issue.
That's why id like to talk to someone that actually owns a new V8. Its seems im the only one
