Looking to start using mirka abranat paper for my ETS 150/3. Saw a youtube video from the UK stating that the 57 hole pad was the one to use versus the 67 hole that doesn't line up. Only problem is I can't find a US retailer that carries it and it's not listed on mirka-online.com. From my search on here people seem to be using 9956 but it looks to be the 67 hole version. So i'm a little confused. Any help would be much appreciated.
