I changed my P-18 rig to a roller furling jib recently. I had the batten pockets re-angled to 45 degrees to allow the sail to roll okay. I haven't seen any performance hit or noticed any problem with the sail fluttering due to the change of the battens. Keep in mind that I don't race, just sail for fun, so I wouldn't necessarily see those little changes that a more high performance sailor would notice.

I'm glad I made the change. The boat is now much easier to deal with when on the dock and launching from the trailer. I also have that little piece of mind that comes from knowing I could reduce sail if the wind suddenly came on too big.
