Full Batten vs Standard Batten

[Gulfsailor]

Buying new sails. 

My loft always recommends our mainsail be fully battened. I've seen others that go standard with partial battens.

I'm wondering, Did C34's come with full or partial battens?

All the original sails were partial battens.

I prefer full batten.  It helps keep the shape especially in lighter air.  I honestly can't see much reason to go partial unless the cost delta was significant and one was severely cost constrained.
