Quoted from Yelobird:
Thats cause you have those mighty swords keeping the ball down! lol Did you do Superbands on the whole machine or just the slings? Never tried them as change doesn't always lead to good things but the Superbands have me intrigued.
Balls rarely hit the swords.
I selectively place superbands, on this game slingshots and superband a post near the pop bumpers, basically places with good amounts of action.
