...........You want your camera slightly bouyant so that if you had to jettison it in an emergency it will float to the surface and not sink into the abyss.
Just my 2 penies worth
Au contraire, mi amigo
my two centavos suggests slightly negative, so:
If it does accidentally slip away, you don't have to chase after it and risk DCS (safer to quickly swim down than up)
If you're on the bottom and you wish to rearrange your gear, you can safely set it down and it won't swim away.
The added weight (however minimal) in front helps maintain horizontal trim (ymmv)
It doesn't keep whacking you in the face
And if it does accidentally sink to the abyss, or float away, just call DEPP or DAN or your favorite insurance provider........
I'm sure there are other pros and cons......bottom line what feels good to the diver.......

btw, if jettisoned or accidentally slips away in any current, will it be worth chasing after on the surface? It will have a pretty good head start if you are careful with your ascent rate..........and you'll have to swim back through whatever conditions are present..........
