That'd be my thought... What say you OILF ???? 4 or not??? All 1/7 & 2 seams........... ??????????
When the time comes- you are doing my DDs skills videos.

Yea... I like how you typed that. I been tryin to tell you guys this for a couple years. I have stuck to the two seam pitch from the get go....even when a Big Time & everyone of DD's coaches tries to tell me I have the tape on the ball wrong. JJ your almost there...
EP: You really want to see more....every pitch I have ever posted of DD pitching is 2~SEAM...
EP: Woops...re-read....Not sure if this is a high enough level for you or not...
Did you read the articles from the two PHD Physicists that say otherwise?
When thrown as a 2–seam or 4–seam fastball (in terms of its orientation rather than speed) the ball did not deflect sideways since the seam remained symmetrical in the y-direction.
And where are the articles?
In Nathan's article, he says, "What I meant to say is that a typical 2S fastball (as opposed to a splitter) has its spin axis tilted relative to a 4S." The tilt of the spin axis is
I'm afraid you guys are chasing unicorns.
I read the article by Nathan and by Rod Cross and they don't say otherwise.
In the Hardball Times article, Nathan says, "What I meant to say is that a typical 2S fastball (as opposed to a splitter) has its spin axis tilted relative to a 4S." The tilt of the spin axis has to do with different release positions (arm position at release) of a 2S vs. a 4S. He didn't make any statement about differences in movement based on 2S or 4S orientation.
The "Aerodynamics in the classroom and at the ball park" by Dr. Rod Cross says:
No deflection = no sideways movement = both have the same movement.
Additionally, the Cross articles refers to two different studies which also showed that seem orientation did not affect ball movement.
In baseball, it is possible for the pitcher to change his arm position at release. Changing the arm position at release changes the rotation axis of a ball, changing the movement of the ball. In softball, the pitcher can't change the arm position at release. She is "stuck" withe arm being perpendicular to the ground at release.
And, of course, pitchers can change the ball through scuffing or applying foreign substances to teh ball.
But, again, simply throwing a ball in a 2S vs. a 4S orientation doesn't change the ball flight.
