(I posted this last night as well, but for some reason the post is not to be found).
If you were given $1500 and the task of putting together the best instructionals library for BJJ/Sub-grappling that $1500 could get you, what would be your picks?
When answering, please only name instructionals concerned with groundwork, as takedowns will be addressed in another thread.
All of Roy Harris's instructionals
All of Mike Jen's instructionals
All of Stephen Kestings instructionals
Matt Thornton's fjkd2
Saulo Ribero's jiujitsu revolution
All of Marcello Garcia's sets
