I checked my wing w/ my incidence meter. The way I check for a twist is to place the incidence meter near the root then move the meter to the tip to see if they match, on mine both panels match incidence at the root and tip and so no twist.

J-P from your discussion it sounds like one of the adjuster pin locations is misplaced resulting in one panel twisted vs. the other panel, so maybe one panel is at .25 degree and the other at 0. This can be corrected at assembly. Perhaps I missunderstand your discription. Maybe you have already contacted Comp-ARf to discuss the problem, if not I suggest you do. I have found their customer service to be ok.
