You also have a choice of fully battened self-tacking jib or a regular roller furling jib - dacron or Pentex. Having tried both self-tacking jibs, I don't think there's is much (if any) advantage to the fully battened jib. We ended up taking out the top batten because we could never get it to shape right (and I tried everything I could think of). Many folks think you can't go wrong with the roller furling (non fully battened) dacron jib - personally, I think they're all pretty even. Do note that if you go with the fully battened jib, you loose the capability to roller furl it.
