I asked DG about testing the bags in DG303, 1998 manufacture date, and
they said to just fill them up and see if they hold water! They claim
no problems is water gets inside the wings as they will drain and dry
quickly. I have not tested the bags in my 303 yet but plan to when I
pull it out of winter storage. Pulling them out is my second choice
and appears to be pretty simple.
