Best pip I've ever used! Switched from P1 1.5mm, the DO knuckle Long 1 feels pretty much like a short pip but maintained the consistency of long pips. It could generate a lot of backspin on pushes as well as completely no spin if you have the right stroke. The chops are heavier compared to P1 with my own strokes (might differ on other people). It feels really good for chopping, great recommend.
