If we assume that the blue puck is where the mass bias line or mark is made fine.
However, for a righty in a stacked drilling the silver and black pucks(let's assume less dense are in the grip. For the same drilling for the lefty the silver and black are towards the PAP.
However, another possiblility and this may be the true picture. Say the black disk is where the mass bias is.
Now on a stacked there is symmetry whether right or left HOWEVER if we assume that the white is the lowest density disk, black the highest and blue the second densest we again have a disparity. Lightest density disk for the lefty is towards pap and for the righty we have the second densest disk towards the PAP. Is this why the righties have the world in my house with their triple xs and we instead on the left just have jumpy with the same ball?
Or is that the oil pattern!
