Yes. A 153 Proto has virtually the same effective edge length as my non-blunted 158 Evo.
Wow. That's quite a difference. Could you elaborate a bit?
I'm not fully understanding how chopping off the tip of the nose/tail gives a more effective edge (at shorter lengths).... my understanding is that the edges used to grip are simply along the sides of the board?
Another way of saying it - how is the edge increased, simply by removing the tip of the nose. No one carves into the snow with the edge on the nose unless you are front flipping... if that makes sense?
