Agree with JeffreyGB. You go too far with so so hands.

I tried to 'Doyle it up' myself just recently. After hitting the wall several times went back to reread the book and was quite surprised of how many things I missed the first time. Doyle's system is a perfect LAG primer - you go AGGRO in small-ish pots and play reasonably in big ones (this is your leak IMO, once the bet/raise is initiated you can't stop), save the flop all-in on draw that is often EV+ due to FE.

On the other side experiments like this really expanded my game and my overall perception of poker as a game. Super System is a great book, filled with tons of interesting ideas and important concepts and those who say it's obsolete are full of BS.
