Saw that shran masood is using 5 string bat stickered up with GN stickers in the tests. Prob using a CA or MB malik bat.

I believe GN Aus introduced it first in the Cobra model from last year - I believe the thinking is that you have a more flexible handle coupled with thicker shoulders to try offset the amount of mass they have higher up yhe blade to balance for the lower middle. That way the bat won't feel too stiff
In my opinion too stiff a handle and you risk shoulder splits (assuming thin shoulders).Need a good balance.
It’s in my cobra review video
