i use a new ball, black widow bite, this past sat nite in my bowling league. it was the worst performance i have had with a new ball in my bowling league. i had two 160s and a 167. my average is 191. i just found out that ball is also a 15 pounded ball. that had an effect on me too. i was doing good with it in practice but at game time i could not get it going. i had so many expectations for this ball. what can i do?
