I've incorporated most of this advice and I'm having great results so far (extremely small sample but I'm up about 3 buyins in about 300 hands). More importantly, I feel like I'm in control again - I don't know why I thought it was a good idea to limp/call w/ hands like J7s - I know some people can play this well, but this just isn't my style, at least not today.

But I still can't bring myself to raise w/ my low SC's and 1-gappers against blinds that defend 30% of the time or more. Even on the button, I feel like I'm better off limping/position betting if I miss rather than raising. Is this really a better way to play them from co or button? And if so, are you just firing 1 barrel at any flop, throwing it away to any aggression assuming you didn't catch a draw or hit hard?
