First, set your tool to 40% in the tool database and unless you are cutting something really dense, like aluminum or brass - just leave it there. It is going to be the fastest/most aggressive setting for pocketing without leaving little triangular islands in the corners.

Second, if you haven't already, go here: http://www.plasticrouting.com/BitSea...?Page=Material and enter in your material (or closest to what you have) and see what they recommend. I do know that Onsrud makes an O-flute specifically for getting a cleaner bottom finish. You're more than likely going to get a better finish using a multi-fluted O-flute vs a single O - spiral or straight. Don't underestimate the advantages of making friends with your local tooling dealer. You'll get better tools at better prices than schmucky retail - plus in many cases the professional answers you need.

Lastly...Use raster for anything that people are going to see. The offset strategy seems to draw the eye to it - rather than your overall design. It has a regular look to it and is much easier to either camouflage or clean up.
