I have both volumes, havent started reading either, just a couple pages of Vol I. I like how he includes real live experience in trying to get his point across (like a hand he played in at the 2003 WSOP final table, etc...)

In GSHE, Volume I is recommended as further reading for no limit rather than tournament holdem (Volume II is recommended for tourney play)

I completely agree with you about being bogged down with the math in Sklansky's books.
