This is just a WAG............but from reading the Specs on the -27
from Schleichers website, they mention making use of new materials. One
notably is the Carbon/Polyethelyne hybrid. I've used "this" material
and find it noticably less robust than regular carbon cloth.

Any thoughts on why this is happening? Based on my experience and that
of others, the ASW 24 has one of the most stable composite wings
around. I hope to get around to sanding mine this winter but it's still
in great shape--even under the dial gauge--and it's nearly 15 years
old. I'm told the '26 is similar. Yet the '27 and now the '29 are said
to be much less so. Did changing to hard tanks from ballast bags
trigger this? Different wing design? Different materials? Is it
happening to every glider out there or just intermittantly?
