It seems we have the answer. CPLR is using his original ZN like foam wings (and who wouldn't want that over composite) with the thick TE's and a TS composite body.
TS seems to have made their own wing with the "old Fashion" if thats the correct term, thin TE's.

Now all of this leaves us with a something to think about.
If CPLR is using a wing with think TE's on a body/wing cut out designed for thin TE's you'll be ending up with the wing with positive angle of incidence! Hummm.
