Not to completely knock the set,but I just think there are better approaches to MMA now then say around the late 90's when that set was made.I have a copy of it somewhere in my house,I'll have to rewatch it.I havent seen many instructionals,I think I have 2 which are Caol Uno's (Which is decent BTW,it's mostly just gettting to see him roll) and Sperry's.
Alot of the takedowns taught in the video are like,old school BJJ style,which to be honest won't really work in modern MMA against guys who know what they are doing. The one problem I have with the Original Sperry Vale Tudo set is that alot of the approaches are taken from assuming your opponent has no clue what he is doing,where as when I analyze certain techniques I like to pick ones that will work on good opponents,and that will work on good opponents frequently.
Not to be negative on the Sperry sets,but I think you can learn more from other sets.I'm not exactly an aficiando of instructionals,because I don't exactly think they are worth the money.However,I know alot of people have learned some cool shit from instructionals,and if you're the type of person that can learn easily from those types of learning devices then more power to you.
