I enjoy using my Gillette and Conard OC. You seem being what is correct. You did not mention your angle. I found an OC requires a differnt angle then for i.e. a SS. I found that you need angle little steeper then a SS. I found passes North to South, West to East, East to West work the best for myself. As far as the lip area I angle the head so thar it touching the lip. I found there is no need for ATG pass.
