Umm that makes them less appealing. The Alu race is pretty damn stiff anyway.
Trying to decided on what to change next season, was thinking either a bigger sail or a lighter boom to get going a bit quicker. Maybe it's gonna be a 9.4 m1 to add to the 8.6
The alu is very stiff so far as ally booms go, but you'll feel the difference straight away when you change to a carbon or vice versa.
Its definitely worth the monetary difference if you want the performance. Weight wise probably not worth it.
