Other issues included poor finishing, crap inserts, delams, lack of proper camber profiles.
I have a 2012, and it is very pooly finished, but I love the ride, it is also totally flat, no camber at all. The new ones are where the old ones should have been.
I read somewhere some of the Jones/Yes boards with quality issues were made at Nidecker's Tunisia factory which I think was then shut down. The better boards were made in Switzerland. I have a 2011/12 Yes Great Beauties that is fine, although it has a spelling mistake on the sidewall - says "great beautys"!! Probably a Tunisian board...
