I bought the basic package a couple years ago. It helped. However, I found that I was able to increase speed dramatically more on the same links by reading (and absorbing into my practice) parts of this guy's book (which is free): https://www.gtroblq.com/book
And a post linked from the book: https://gtroblq.blogspot.com/2018/09/slant-picking.html
There's also a Facebook group (approval required) where he answers questions directly.
That said, as I mentioned, the Troy Grady stuff helped me. I don't regret the purchase. Troy's invested a lot in analyzing and presenting the playing of a lot of top-flight guitarists. I intend to continue using his stuff - but now, I'll be doing it with a somewhat different approach than he's showing in his demonstrations.
YMMV and all that.
