I think multi-tabling NL is ridiculous. Your'e going to lose a lot of information on your players and probably lose all your bluffing moves completely. No way you can notice all the players betting patterns and tendencies. Your'e underrolled as it is and playing all these tables will burn your money away. You need to play both the players as well as the cards. I would suggest reading HOH1 and HOH2 if you havent already they have helped my game out a lot.
