NO ONE is OAT-free... are you kidding me? I do agree with your first part though However, some times you need to be able to flip a stable/overstable disc that you may not have the "arm speed" to flip... Not all OAT is bad. That's all I'm trying to say.
Not saying I am, or anyone else is, OAT-free, just preaching physics theory. And, I'm well aware of inducing OAT on purpose, and it's super useful, but it's also a very advanced technique that I don't think we should try and teach someone who hasn't yet gotten standard hyzer flips down yet.
