Haha, is there any reason for that scalloped backing plate? Or is it just to make the polisher look different from competitors' products?
As long as the weighting would still be OK with different backing plates, that's fine with me.
Anybody know if you can switch the BPs out between a 5000 and 6000? In the UK we're getting the 6000, but I think a 5" BP would work better for my needs.
