Depends a lot on the nature of the thermal. Weak, crummy, narrow and
turbolent ones favor some gliders while strong, wide & steady ones favor
other types. -And then, of course, it depends on the wing loading, some
types are good climbers at other wing loading ranges than others.

- Actually, the above is just useless theory. In the real World, the Libelle
always climbs better than anything you can throw at it ;-)
