Not to beat a dead horse here, but one thing I think someone is missing is that though you increased the wing area, you are decreasing wing loading, and I believe that in itself would be compensate for the shear and bending moments mentioned earlier.
Fred Johnson Reno, NV Dan Heath wrote I know this has been noted before, but I will repeat it. The Diehl wing skins are significantly longer than the stock wings, and there is no "beefing" required, and I know of NO incidents attributed to the longer wings. I have them and the wing span is 23'6". Mark, you don't have to worry.
