well i am a lefty and have an inferno, i love the way the ball rolls and hits but my friend, who is a righty has a problem with his. everytime he throws it it sounds as if it is rolling over a hole or fingers or thumb, but when we look at the ball there is nothing. he isnt the only righty to have this problem, two other out of town bowlers that i do tend to bowl with at tournaments have the same problem with their inferno. i know three other lefties and they do not have this problem...what could it be
