I dunno, that really doesn't look like whiteworm to me and i should know as one of my wheels is infested with it and the other 3 have it to a lesser extent. It tends to be more wormy or squiggly!
Agree with the Doc, I love these wheels but they're just not practical or even easily repairable. The vancouvers on my upcoming GTD won't have the same wow, but hopefully they'll still look decent after a couple of years!
