My personal opinion is that cutting corners is wrong.
It's done to reduce lean angle or to get from A to B as fast as possible.
There is much more to learn by staying center lane - as soon as you drift away from center, you know something wasn't going according to your plan. This feedback will tell you what needs to be changed.
Cutting corners work well on the track, but if you do it on the street you use most of your error margins.
If cutting corners is a required technique to get you through, you went in too fast or are not able to lean over enough.
Don't get me wrong - I do it too, but I make an effort to avoid it.
I recommend finding Nick Ienatsch's article "The Pace".
Very wise and very fun technique.
In my opinion
