Picking perpendicularly to neck?

I think I might have finally found the breakthrough I needed - I’ve been playing with the aim of picking perpendicularly to the neck for about 2-3 years, thinking that it was something I needed to do - I’m starting to realise now that it could well have been a red herring that I got stuck on. Is this necessary or not? I have noticed an immese change in the comfort and fluidity of my playing when I don’t worry about that.

Are you talking about edge picking? If so, it definitely reduces the resistance when you’re picking.

Nah, I edge pick quick heavily regardless - I’m talking about pick direction in relation to the neck.
