I know what you mean, and at times I have the same discussion with myself for a few days after a game....
I think you may be bitting off a little extra with Super System. That's a lot of book for the first or second read. I might suggest Warren's "Winners Guide to Texas Hold'em" there are two versions. Start with the smaller one, then the larger. A fantastic book I just finished, (actually now that I think of it, you should start with) is called "Winning Low Limit Poker" GREAT book for the limits we play. I'd next go to Doyle's book I mentioned earlier, then Caro's book "Winning Poker Secrets", next "Caro's Book of Poker Tells" , then I'd get into into the Super System's and such.
Just a thought on reading, but as with anything grat what ever peaks your interest and go with it. Those are books that I liked and found value in.
