The good thing about Etchells is some people keep buying new race sails regularly and the old stuff makes good buying. The jibs are particular good if your after a blade headsail on a quarter tonner. The tricky bit is getting a block forward enough on the deck. The only problem I had was the tape hanks stopped me lowering the sail enough on the fore stay when trying to pick up a mooring, wind would just blow the nose away. The mains cut down suit a lot of smaller yachts too and they are always well made sails.
Just looking at the main on a walker H28 not much difference to a walker main
