well, to improve our bowling is actually just train, TRAIN and TRAIN!! actaully thats a common sense thing..[I'm talking crap again]haha:] maybe we can start from the basics of bowling first like 1) aiming and targetting goals+ achieving the goals 2)rolling the ball then when you are familiar with it then practise spining the ball 3)calculating where and at which dot or arrow should we stand to aim at
here are some crappy bowling tips from me, the bangsai..
1) to spin a ball, start by swinging the ball with flat palm then when you are about to deliver, change the direction of your palm straight
2)make sure that the angle when releasing the ball is not too much
3)when delivering the ball, your back should be straight [p.s: don't follow me, I'm a bad example]
4)aim to see which dot or arrow you are going to release before you deliver the ball

well.. thats all I can think of. HOpe that I'm of help to you all! jiayOus everyone.. make our schOol stand out and proud!! =]All tHE bESt..!! swiss bowlers, swiss bowlers, go..GO..GO!!!
