Thanks for the compliments guys, we appreciate it!

Wouldn't it of been better to put the fitting as high as possible in the can so in the event the motor pushes out a ton of oil, the oil can fall out of suspension and fill the can while the gas escapes?
The only reason I am saying something is I have seen a similar style can setup be very ineffective during a motor issue.

Tuna:
There are several reasons, and you bring up a good point for discussion.
Your concern with the design was discussed before we did it. My thoughts on the matter:
A) Our vent channel on top of the VC draws air from above the factory baffling (which is very well designed) that is already in place.
Since it's located on the top of the VC behind the factory baffling, there will be zero oil pushed into it due to puddling/splashing/acceleration/etc as seen with VC vents that are located on the front or rear of the VC.
So.....that eliminates one of the normal "issues" with typical venting schemes. This design will carry less oil into the can than usual IMO.
B) We tried several different routing options for the A.N. fittings and line, and this routing provided enough flex in the line to be able to remove the line easily, and looked the best as well.
C)

In that event, the whole VC would have to fill with oil to the top to start pushing into the can. That'll never happen. And if there was that serious of a motor issue, you've got 2 quarts catch can capacity for a reason. Besides, you'd notice something wrong at that point and shut it down.
If the catch can did fill up enough with oil to start filling up the A.N. line in normal use, it'd still push or "bubble" the pressurized blowby into the can. At high speeds/loads where there is a lot of blowby, this would be much like a steady stream of air and I feel the can would still be every bit as functional.
There is a fitting under the can that can be accessed in the wheel well to drain it easily, and an internal baffle in the can to knock oil in the airstream out of suspension as well.
So...we will see how it works out. If it does need some reworking we will do so, but I think it'll be fine as is. We will see!
