Well, they are supposed to improve low-speed handling and thermalling
performance by reducing induced drag, while not costing anything at the
high end of the speed range. I think they actually do improve
performance as advertised, but I don't have any hard data to support
this, other than the wind tunnel & flight data obtained in by the folks
who adapted the LS-8 winglets to the LS-4.

I would not think it possible to significantly improve the handling and
thermalling of the LS-4. It's already so close to perfect in those areas
that any improvement would be vanishingly small.

But hey, they *do* look cool! ;-).

Absolutely!
