Good idea Garland, that will work.
For everyone: If you don't find that you can make things look exactly the way you want, don't worry about it. For example, if you've got 16 perfect holes and the 2 holes that are perfect but for a flaw that could be fixed by shaping, you don't have to re-route everything, or try to get the shaping to look right. The judges will take into account that you might have a good routing that gives the most good holes possible, and that some "earthmoving" would be required to complete the design. If you want to try to do some shaping, go for it, but try to worry about the things you can control for the most part. That's just advice, not a design directive or anything, because the point is for you to have fun with it, whatever part of the process you enjoy most.
