I agree that Super/System is dangerous for inexpert players.

When i first started getting serious about learning to play i read S/S and came away from it seriously overvaluing suited connectors. I still do a bit.

Even in the intro to the section he says something like "these hands are the reason i play poker"...

anyway it took me a while to realise that they're only as good as he says if you are dominating the table or can get in a cheap flop.
