if * indicates pin postion, it appears to be set up for a rt. handed bowler. would appear to be a early rolling set up, not sure about the pin balance hole. i also bowl with an inferno (pearl), rt hand drilling. with this set up my ball is very aggressive , not long as anticipated, ball track on the low side, higher than average revs. good ball. * pin
