she has high tilt but i don't think she's a spinner. Spinners purposely have their hand in that position and aim to go brooklyn with a ball thats about 12 lbs or so, parkins uses a 16 lb and she does have more tilt than spinners

There are degrees of spin.  Anything that tilts the axis, and decrease the track size has some degree of spin.  When I was young and learning my game, we referred to the most effective release as a semi roller, contrasted to a full roller, or spinner.  I started my thumb at about 2 oclock, and rotated it to about 10 oclock.  Something along those lines was done by most every scratch bowler to a greater or lesser degree.

Other than the helicopter release, which by the way is used with a 12 lb ball, any type of traditional swing regardless of how much wrist rotation and spin is put on the ball at release,  will transition to roll as it encounter friction.

Parkins was throwing a semi-spinner.  Goes long and hooks late.  Effective on the right condition.  She won her match with it.

That is kind of my point to this thread. With today's very aggressive coverstocks, I think a semi-spinner could be very effective on today's conditions.

correcte.  A spinning type of ball will not be abe to effectively "read the pattern" on the longer flatter pattern.  This is why people who top the ball struggle so much on longer patterns.  On a THS, it could be devastating with a 12 lb ball.  That is if you could stand the ridicule.        

On heavy, flatter patterns the semi-spinner will not fare as well as someone who rolls the ball with higher track.  Who said anything about fresh THS patterns?  No matter where somebody's ball tracks, feed it to the dry outside boards and it comes back.

Exactly the point I was trying to make.  Thanks

My view on this is where I used to see spinners struggling, it seems with all this new aggresive equipment available today, that this style might work on all conditions.

You might have a point, but I would like to see it in action first. Give these Semi-Spinners a Guru or some kind of high end monster ball of today. Put them on that high volume flat pattern. You might be surprised.

Its not about style of the bowler on high volume flat pattern. Its more about the bowler's ability and skill set that makes the difference on that pattern.

Its the bowler's ability and skill set that make the difference on any pattern.  Anybody who bowls can tell you that changing the axis of rotation of the bowling ball is what gets you thru different patterns and oil length.  A semi spinner release is from timing or the lack of strength to stay behind the ball.  Since it is not a desirable release to have as "A" release it stands to reason that one that throws the ball like that cannot change to adapt.  Therefore they will struggle on everything but shorter, dryer patterns.  Its just that simple.

Watch the guys on the show.  I cannot think of one top player from Rash to Weber who hasn't gone toward more forward roll and less axis tilt on the tournament patterns.  lack of friction kills spinners.  Even with the aggressive shells, heavy long oil takes away the friction that a spinner needs. 

Weber more forward roll? must have missed that style change.
