Title: Mass bias in track
Post by: xman868 on November 02, 2014, 07:52:06 AM
Recently got a suggestion from my mad scientist at the pro shop that I should try a layout I've seen very rarely. Pin over ring finger, MB in track area on a Defiant Soul.
I am slightly rev dominant, 16-17 mph through fronts, PAP 5 over and 1 down          ( inverted ) approx. 380-400 rpm.  What will the motion/ characteristics of this layout look like? 
Thanks in advance for any responses.

Depends on your stats, lane conditions, ball and surface prep, and the dual angle to your pap. Generally, the ball is going to transition later depending on the how far you are sending the PSA in the track. Again, a lot more goes into it than just your general stats. Your PSO has come up with a layout so that's upon you and them.

Although everything in the previous post is spot on, from a layman's terms, when I had my stuff with the mass bias in the track (usually just to the left of my thumb - right handed) the ball would not have a hockey stick shape and would be a smooth arc.

Generally, the closer the mass bias is to your track, the smoother the ball, closer it is to your PAP, the sharper the backend. That is a very general-loose statement.

The higher the dual angle sum the longer it goes before transitioning.  Mass closer to the track is a higher sum so later transition where mass closer to the val would mean lower sum and earlier transition. Smaller val angles give you sharper moves at the break point.

Thanks all for your responses. The layman's terms help a lot. Any other feedback would be appreciated.
My goal is to be able to move my feet right on a fresh pattern and be able to create straighter angles through the front without using weaker equipment.
My natural release tends to make balls read violently the more I move right unless there is massive volume up front. My inverted track seems to be an issue here also.
Any other options to achieve this would also help...Thanks

more than likely the reason you see the smoother shape when drilling the mb in the track is the pin to pap distance not where the psa is. your drilling angle is high which will get it to transition later but your pin distance is also probably high causing the ball to roll more forward

Considering I had balls with pin under ring, over ring, and in leverage, and pin near my PAP all with the mass bias in the track and others with the mass bias in the same pin positions but closer to my PAP, they all were softer on the back when I had the mass bias in my track. Obviously different results for different styles, etc, and thus why I stated a loose generalization.

If you put the mb on either side of the thumb withen 1/2" in most cases the psa will end up in the thumb. Just something to consider.
