Is it necessary to read TPFAP if you plan on getting HOH?

Obviously when TPFAP came out it was the best book written on the topic but now people say HOHv1 and v2 are the best on the topic. So my question is, is it necessary to read TPFAP, or is HOH all you need to read on tournament poker? I ordered TPFAP using my VIP points on Empire, so I'm basically getting that book for free, so the chances are I'll read it no matter what. From the reviews I've read HOH covers what Sklansky discusses and then some, so I'm under the impression that reading TPFAP isn't all that necessary any longer, am I wrong?
