Well, it is like this... Let's say a friend of mine is bowling well with Brunswick equipment but wants to try other company, let's say Storm. What would he experience? He's an average player (if condition is easy he's on the low 600, if difficult can get a 570) and improving. Will he lower his score in the process of understanding the new equipment's reaction? Nothing should happen to him? How would you describe the difference in reaction between these companies?
