Upon much closer reading of your op and inspection of the pik of your bike, noticed what appears to be a stripe around both rims that could be where the pads have already worn through the paint?.
Or is it a decorative pinstripe, tough to tell from the picture.

Is the pik of your bike in the op showing the Swiss Stop pads installed, or an older picture? Pre swiss stop?
Could you supply a picture of the upper 30-40% of both rims, face on to the rims and centered on the new brake pads?
