Finished SSH....next book should be...?

[SmileyPSU]

Good evening all,

I used to be an extremely tight low-limit player and while that approach always slowly but surely made the money, I've read SSH, applied its principles to my game, and the improvement has been tremendous. I cannot speak highly enough about that book.

I just finished SSH and my question to you all is which book should I pick up next? I'm actively trying to improve my game, but still only comfortable/bankrolled enough to play the lower limits (.5/1, or 1/2 if I see a soft enough game). TOP, by all accounts, appears to be the best poker book ever written, but would the advice I find in that book apply to the lower limit games that I currently play? Is there another book I pick up the next time I'm at the mall that would be more beneficial for the stakes that I play.

Any advice is greatly appreciated.
