I think there is still some debate on bar shape- some see straight ends. Regarding grips, I think the consensus is seven with angled cuts on ends. However, I don't recall the angle- experts: is it 30 or 45 degrees?
If we use the ANH V1 pics for reference, I would say anywhere between 22 and 30 degrees but no further. However, I have cut grips where they feature a gradually rounded angle as is seen on the V1 prop along side the sharp, chiseled angles.
