I, admittedly, think you could be better served. But with HoC, you will learn the basics, I guess. There isn't any bad per se in them. But I think it teaches too nitty of a style. Again, this is most likely due to my style of play being different.(This is most likely because my primary game is/was PLO and PLO8, I chose my NL coach based on what I was comfortable with style wise).
I think you'd be better served taking the cost of 2 books and buying a month of Dueces Cracked (in no way affiliated with them, just my experience). You'd have a month to watch and download enough vids(series), that you would keep the learning curve going for a longer term than what the books would teach you.
