I don't believe "helping" english is really a thing, but if it is I think it's the other way around. It should be the kind that (supposedly) spins the OB in off the far pocket facing - in this case that's stun, or inside (right/counterclockwise) english, which would spin the OB left/clockwise.The stun could cause it to rattle. Using the same speed as the stun shot, but with a touch of outside/"helping" english
