I tried the SB limp strat, but realized it wasn't worth it as I wasn't gaining much with the bottom of my range, missing value with the top, and playing the middle of my range much worse postflop.
The one good thing about the open complete strat was that it made regulars uncomfortable from the BB because they hadn't constructed a good strategy yet. Of course, it would only be a matter of time before they just realized "hey I should raise like 40% of the time here and smash this guy".
2/3 it has some merit, but I'd still prefer raise or fold if there's any semblance of preflop fold equity.
