I like some of their stuff very much.
Some of their books i couldn’t get to work for myself, so i leave them for others to do. I don’t blame them for that, it’s just my worldview is too different to make a match.
There are a few of their books that are keyscaled wrong to my way of thinking; their logic isn’t logicking the way mine does. I’ve corrected the keyscales for my own understanding on a couple of their books and they made perfect sense to me, so i guess it comes down to whatever makes sense to you is what you should use. There’s value there, you just have to work within a magical pardigm and format you can believe in.
That’s just my opinion, which means nothing overall. Opinions are like assholes, everybody has one and most of’em stink.
End of the day, whatever works for you is fine by me, i have no agenda or ego when it comes to this stuff.
