Only one point on the cover rubs the chainstay at a time (which varies), so it's not a clearance issue as such.
I can tune it out doing as you suggested, but it soon returns. Unfortunately taping it to the rim isn't a practical option, as the cover has to come off quite regularly.
That's all my tricks done I'm afraid. Some guys on the TTF said they'd drilled small holes and zip-tied the covers to hold them inwards towards the spokes but I didn't want to drill them.
Felt B12.
