There are plenty of used foam battens out there, they were used on the P-16, P-18, P18-2, P-19 and almost all of the nacras, if you are looking for only one or two, you should be able to find them with little trouble. The difference that is probably the most is weight. With fiberglass battens the weight aloft is quite abit more. Just let people know the area you are from and you should be able to replace the foam batten pretty quickly.
