Bob quotes:
"As to doing the 0/0 take off thing, perch your aircraft on the deck edge of an elevated heli-deck offshore on a nasty night facing away from the Rig/Platform and any visible light and tell me about a visual transition to instruments after being at Vy and above MSALT! The instant you dip the nose on takeoff you are off into the Black Abyss. Every North Sea Offshore Pilot knows that as they do it very often."
You beat me to it, Bob. All this talk of attaining 50 kts before going IMC ... the most uncomfortable regular take-offs I ever encountered were in the 61N on the North Sea when after lifting in the turbulence on a Forties platform in the brilliant glare of the gas flare one then headed into complete blackness whilst gaining climbing speed, and then maybe had to repeat the exercise several times if one was on a "shuttle" when one had to repeatedly go from visual to instruments and back again.
