Is there a jib with battens that you can furl? Skip at EP sails says they only make one jib with battens for the 20, and if people are furling them they are shortening the battens. If this is the case how much do you shorten the battens? and will the sail completely furl?

There is no full batten jib that you can furl. All of the roller furling jibs have mini battens that are nearly vertical in the leach of the sail.

So they don't sell the furling jib anymore?

They do sell the furling jib still, but there has never been a full batten roller furling jib-it's not possible.
