But I think it works wonders the other way round, people with pakour / free running or acrobactic background tend to progress a lot faster doing the extreme tricks.
However looking at newcomers these days, I believe by watching vids etc of other people and taking on board the advise of those bocking a little while longer, the learning curve is a lot shorter than it used to be and a non bocker can be flipping and doing other tricks within a couple of months in some cases!
