Sarah,
If you have FXone's locally then you probably should go that route, BUT the FX one is not the most forgiving boat (I have been told) in the bigger winds - I considered one to replace my Inter 17 that is currently for sale. I've removed the FXone from my list (Currently an A class or something line it, a Shadow (UK Based 16 footer) or another Inter 17). as it just does not appear to perform to the handicap it has.
Good luck with what ever you decide
Cheers
Simon
