Homebrew PCBs

Hi All,
       Somebody asked me about traces that run between pads. This
I feel is one of pitfalls of milling PCBs. See the photo in
the KLEINBAUER folder. My new board only has 12 traces that go
between pads. I now have a few options. 1 Don't mill boards so deep. 
2. Make pads smaller and drill with a different bit. As you can see
in the photo, the traces are there! I can use the board for test
purposes. But unless I can get the trace wider, I can't sell the
board. I mill the boards deeper so they are easier to solder.
