Changing armswing to match lane conditions!
How many of us only change balls,lines,targeting techniques,hand changes,
and leave out swing change.If you are bowling league or a tournament,
and see a certain player ripping it up,and you are not ,do you ever
try to emulate that players style?Also would you know how to?

Each swing style changes hand motion and ball angle.You have to know how
change swings in order to keep up with the lanes if you are not scoring
with you style.

The wrap behind the back swing will cause the hand to come around ball.
This release creates more rotation and less roll,this works better on
drier parts and from the inside line than it does it does on heavier oil.

The bump-out armswing places the bowlers hand behind the ball.This gets more roll than it does rotation.This works well for playing a track,and for
conditions requiring you to be accurate,and for oilier lanes.


The bump swing that tucks back under creates an almost straight swing
when it comes back through.This swing will let you play straighter
up front through the heads.which lets you play a more down and in shot.

The swing that is wrapped around just a little behind your back,with open
hips and a open shoulder lets the bowler play out into the dry area in order to open up the lane.

Or the straight swing,which is essence still goes out just slightly and tucks
back under.

If you want to see one of the best at changing their swing line,watch some
videos of W.R.Williams Jr.

Now before anyone has anything to say about the styles names,I know
that the USBC is trying to tell everyone that these names are now
different .
Four inch groove or tuck.
Pro groove or tuck swing.
Tuck loop.
Reverse loop. Straight.
