I currently have a roller furler on my 16 with the standard jib. It is coming off today! There is a noticable performance difference when you have the battens out, and I would say even a greater tendancy to pitchpole. Also, the luff flutters alot, and it really beats up your sail. You also lose the ability to adjust the tension of your rig using the jib halyard, since all this is removed. If you still want to try it out, you can find my setup on ebay sometime next week.
