snug 'em up and forget it, especially if they're EP (Elliot Patterson) sails as those were a fuller cut.
I would add that most of my experience was with the EP mainsail, which I prefered to the later Hobie sail (although I didn't sail the Hobie much). It felt like the EP was a lot more tunable. It had a fuller cut, but the luff was a little shorter, so you could crank on the downhaul and make it flat as a board- a lot of range.
The Hobie sail seemed like a much flatter cut and the downhaul would just bottom out before you got much tension on the luff (of course I never adjusted the diamond tension between the two sails, so that may have been part of the issue).
Anyway, I agree, if it's an EP sail, there is no need to stuff the battens in beyond taking out the wrinkles.
