When should I start reading TOP and HPFAP?

[will778]

Since these books consist of advanced concepts should I wait until I move up to mid level stakes before reading them? I'm afraid after reading these two books I will start to give micro/small stakes players too much credit in their plays.

Also, I've read SSHE and a few other non 2+2 books, should I read Hold'em Poker? I've read that Hold'em Poker was a beginner level book and that it should be skipped over for SSHE since they both contain similar concepts. Can anybody who has read both books shed some light? I'm just curious if there is a significant amount of content in Hold'em Poker that isn't in SSHE already.
