EV of blind steal vs play for different hand ranks?

[gasoltub]

At what rank does your hole cards in Holdem have less than 0.75BB EV?
In other words, at what rank is a successful blind steal more profitable than calling/raising and playing the hand?

I know it's impossible to say exactly but there is perhaps a reasonable estimation.

Obviously having everyone fold after you raise AA UTG is depressing, but how about JTs from LP? ATo? Other hole cards?

I posted this in Poker Theory yesterday, but haven't got any replies so far so I'm giving it a shot here.
