if we want to carry the kite higher than it's designed for, we let out 5-8cm on the tack line and sheet in. So far we have used this technique to good effect in distance races when the wind isn't too strong (dont try this in anything near trapeze conditions). This small change really alters the shape of the kite and is fast up to a certain windspeed.
Agreed - but why not ease it while in trapeze conditions? We do it often - especially distance racing.
