Whose Preflop Reccomendations Do You Use?

[12AX7]

Hi Everyone,
Been going through the process of trying to get my preflop game together and was curious whose reccomendations you prefer for various online levels at the various online cardrooms.

SSHE, HPFAP?, Lee Jones, Hilger, something else?

I realize Ed M's statement is (parphrased) "just pick one, use it, adjust it based on game conditons... don't call raises with offsuit junk". Which is no doubt valid, since all of poker is pretty much and "it depends" sort of situational analysis.

Thought I have to admit, there are time when Ed writes, "...which is clearly a error..." or "...way to profitable..." etc. and I wonder how those facts were determined, exactly. (Experience, monte carlo sims, plain old probability calcs?)

I'd really like to be able to look at a hand, and a situation and be able to determine that myself, rather than simply storing as many of those tidbits between my ears as I can.

So anyway, what are you folks finding effective at various limits and cardrooms?
