Any difference between 2009 and 2010 Zen besides color??

Flex, construction, thickness, fins, inserts…..etc

Thanks!

One difference is that the 2010 model is supposed to be lighter than 2008/9

I guess what I really want to know is which would be better for putting wakeboard bindings on.

Does the 2009 have inserts for bindings or will the 2010 be a better choice??

The 2010 larger size is the best for attaching bindings. It has been designed for that purpose.
