Hmm, the concensus so far is leaning towarts Slanted.
I have an Arkanoid and Crystal Castles and they are both slanted. About 10 degrees.
Subzero has an interesting comment though. I'll have to mock up my CP slanted and see how it feels.
Fredster, that was interesting. Never thought of spilled drinks and smokers. There will definately not be smokers using this cab, but I can't say the same for my kids drinking around the cab while I'm not around (and I don't mean beer)

. It would be nasty cleaning coke out of the cab!!!
Thanks for the feedback so far guys...
