Comparing Sklansky in SS1 to Zee's Hi/Low Split - The Trap

[TomBrooks]

I have read through most of Sklansky's Stud 8 Section in SS1 and Zee's Stud 8 in HLSPFAP. I am far from having it all down pat and certainly need to go back and review both, but in the meantime I have one initial impression I'd like to ask about.

David seems to emphasize going for low and avoiding all but the best highs a lot more than Ray. Ray spends a fair amount of time talking about high hands that are playable.

Are these two works esposing different theories, or are they congruent in a way that has just escaped me so far?
