Well, AFAIK, these 'banana' shaped tips (for lack of a better term) were
never made available in the US. Martyn did very well against the N4s,
ASW22s, N3s, ASH25s, and others IIRC. He flew 'hors concours' but would
have placed 1st handicapped and 5th scratch as the scoring went. That was
out of 45.

I don't know, I called Martyn when I bought my LS6c-17.5,
his comment was along the lines that upgrading to the
18m or 15m winglets from the straight 17.5 and 15m
tips wouldn't be worth it for the marginal performance
gain.
