Lane is correct. Although for those who collapse their wrist at release (E. J. Tackett, Wes Malott, J. Belmonte, etc.), having more, rather then less forward spine tilt allows them to rotate their fingers through more circumference of the ball , creating more
natural revolutions with little effort.
On the other hand, a (side-of-the-ball) stroker style bowler needs to maintain a somewhat more erect posture at release to avoid rolling the ball with too much axis tilt (since they are on the side of the ball at release).
Also, too much early spine tilt can often cause the bowler to "chase" the ball, resulting in poor timing and lack of leverage.
As with most everything, this is not a one size- fits all. Generally speaking however,
those that throw with 2 hands, and those who uncoil their wrists at release, do better by utilizing quite a bit more forward spine tilt than those who release the ball
in the old suitcase position (Like Liz Johnson). Everybody's abilities are different in determining how much tilt they can comfortably deploy without risking
their ability to repeat consistent, quality shots.
Good luck!
