I have an interesting story. Most of you guys from the western countries only know bowling with straight ball or hook ball. But in Asia, especially in my country, Vietnam, there many many bowlers using Spinner style or UFO style bowling like this: https://www.youtube.com/watch?v=dfuXQsbmlyc
The reason why as I know so far is that because the lane oiling condition and lane maintaining in our country is so bad that bowlers tend to use spinner style to minimize the risk and get high score. Hook bowlers seem to struggle a lot when lane oiling is so poor and especially we don't know what oil pattern we are bowling on in advance.
and in reality, spinner styles can beat hook style though they don't care about the 6 degree fundamental of hook. They just throw and strike. And currently the Champion of QubicaAMF Bowling World Cup 2016 - Men is a Spinner! - http://bowl.com/News/NewsDetails.aspx?id=23622328082 So does it make you think of hook is not an optimal style to bowl? And when the lane is so awful that you can not get 9 with a hook shot, do you think you should switch to straight ball and throw a bullet?
I am eager to know your opinions.
P/S: I am a hook bowler
