I can safely say that there is one major reason why i would never shoot an A1, and that is since the grip frame is that small that my hands cannot pull the trigger properly in the most comfortable position for me.
Shame really though since they are nice guns, but i really do doubt that I would ever choose it over my ego, before someone says something along the lines of yeah but angels can shoot any paint, I used my ego all day on sunday, didnt have a barrel break or chop all day, but the even the people using a1s with the same paint and insert did break some paint inside their marker
