Hal & Skip -
Sorry if I wasn't clear about it. When I said "Professional" I meant 1A2 professional - i.e. if you were ever going to use the wiring for another similar system. Obviously the cleanest looking job is the most professional. Having 23 pairs taped up on a wall is going to look like hell as is a mated pair of amphenlols hanging out of a hole in the wall.
I would definitely use a flush mount wall jack to cover a hole in a wall and on an exposed wall I would mate a 153 adapter to the existing amphenol and cover it with a SE-700 housing - if they're still available (I think that's the right number).
It's good that you guys are paying attention and keeping me honest. Too often I know what I want to say - I just don't fully explain it.
Sam
