I've been researching and trying different bits for the waterline finish pass and the pencil finish pass and can't get quite the quality I want.  I'm sick of spending time and money and would appreciate some help.  At the moment for about a 15in.x10in. carving I use a 1/4 in. Straight 2 flute bit for roughing, 1/8 in. round tip bit for x and y finish pass & waterline finish pass, and a V shaped bit with about a 1/32 in. wide tip for pencil finish.  The V shaped gives the carving nice detail but leaves noticeable grooves and dots throughout the carving. 

Anyone have any advice on bit selection?

If you don't use the same tool for all the finishing passes, you're going to have noticeable differences between those areas. I'd try a 1/16" or 1/32" ballnose for the pencil toolpath. But this can vary greatly from model to model. You might want to ask on the MeshCAM forum what bits people are using, and post some pics of your model.
