My original design had the slant of the cp at 12 degrees

As I kept trying different control designs, I thought 20 degrees was pretty comfortable.

Most of the people I have built for dont play head to head, but would rather have it in the corner of the room as a jukebox/multiplayer... having it only be vertical limits the amout of people who can play games like gauntlet and other 4 player games without taking up a huge amount of rec room space. Usually the finish gets matched to the pool table.
I am so glad that Andy finally is selling a flushmount trackball (even if it is a 3") because routering out the wood panel to get the top mount in really sucks. I got mine a few weeks ago and it is pretty nice.
