To be honest it depends on how confident you are... My view is this, get Mystery's - MM book...
Again it depends theres tons of theories ... I've not had the patience to sit and go through them all... I like Mystery's ideas, his and James Matador's approaches and have found them to be very successful so for me I've not needed any material.
All I own is - The Game and Mystery Method. The rest of my material is magic, showmanship, things like mind games.... I know how to "pick-up" so the last thing i need now is a million and one theories, if one works why look for others... I guess its only if you're not comfortable with MM.
But there you go
