A fun ride...

a FEW observers who only know their own system can be very dogmatic

I won't deny that, doing it "by the book" is all very well, but even the book says that the System it teaches should be applied flexibly rather than dogmatically.

and again IMHO some of the things taught by IAM are just wrong (road positioning for corners for example ,great if you only doing an isolated corner very unhelpful if you doing a series of opposite direction bends)

I'm puzzled by this, I'd like to know what you mean here.

That said training is better than no training but shop around

I agree entirely.
