Not sure what kind of info you want. I have both books, though its been years since Ive gotten into them. The one book has material that is toughermuch tougherthan the other volume (I cant recall which is which off the top of my head; and Im not at home). What I best remember is the Marlo-esque style of the instruction; very involved. The material is not necessarily original as far as plots go, but mostly his solutions.
They were not particularly well produced: The volume with the tough material fell apart on me (from having it open trying to follow the material. But I suppose that doesnt matter much. I got the easy volume in the after market. Apparently it originally came with some gaffed cards, but I did not get those.
Thats about all I can recall at the moment.
I dont have much else to say (I know nothing about Mr. Branch).
So would I recommend them? I suppose it depends on price. Card enthusiasts have plenty from which to choose, and I do believe in studying as much as you can if thats your thing. However, I have not been compelled to revisit them.
