Older X9 have problems with grip.
Some have front part cracks http://www.windsurfing33.com/forum/v...=36338&start=2
Some have front cup brakage, replaced with X6 ones, or by using Streamlined or MS boom head
But when strengthening is done, it's a top boom used by a great number of racers.
On the 2010 X9, boom head has been changed, wait and see...
Other choices :
- Maui sails, heavy but strong & Stiff
- AL 360 E3 Carbon, lightweight but as stiff as MS and X9, more carbon inside (-: ( 60% for X9 )
For durability, no recursive problem related after one year
The first brakage in december by a more than 100 Kg guy, who killed a Fiberspar carbon Wave + X9 Wave + Platinium slam in 2008
Changed by AL in less than a week.
Previous generations dont have plebiscite.
