Re bow reenforcement, and oil canning. Some years ago, the issue was raised in the NPYOA newsletter and Bill Shaw, the Pearson designer addressed it. I’ll see if I can find a copy. If I remember correctly, he recommended additional layup of a layer of mat, 1/2″ balsa core then a couple layers of mat and woven roving.
