Honestly, I'm good at bowling :DD
....yeah, I pretty much throw the ball.
........and look like I've dislocated most of my joints.
At least you have the fingers in the right angle :)
For some reason, I got used to bowling with my thumb at 6 o'clock and the fingers at 12 o'clock. Since I consistently get decent scores (releasing from the outermost right side of the lane, aiming slightly right of the middle cone), I haven't bothered changing to the "correct" technique no matter how many times people tell me that it looks weird.
