ASW 20 wing tip extensions

Can any advise me on the availability/ where I could obtain, a set of wing tip extensions and winglets ( if possible) for an ASW 20

Thanks Ross Biggar

M&H if you are talking about 15M tips.

I cannot say enough about how positively they effected the performance of my 20 (better roll control on takeoff, slower thermalling speed, etc.) Of course I sold it and got a Ventus because who cares about winglets if you are about two pounds short on wing loading? : )

M&H Soaring!!!!! here is their link. Good prices and great people. http://www.mandhsoaring.com/links.html
