Curious why he compared a pin up 3.75" pin to pap to a 5" pin down.  Seems the flare in oil of a 3.75" pin to pap for a pin down would be similar distance in flare when migrating in oil vs dry of the 3.75 pin up.… .and a 5" pin up would decrease flare in oil distance to dry like the pin down.

What he said about symmetrical has been true for decades. What he said about assyms has been true for decades. What was really informational was the talk about migration. That tickled the nerd in me.

Axis Migration is fun. If the customer is willing to put in the time and the money, there's a lot a pro shop operator can do to help their game. What's amazing is he continues to talk about the same information for now decades and its like the public takes it in piece at a time lol. Whats even more amazing is we had a post about plugging a weight hole and "magically" getting more back end motion. This continues to prove, STATIC WEIGHTS DO NOT MATTER in ball motion.

One day, I'm going to go into the lab and focus on this stuff. Thinking about building a small shop in the basement, so your guy ID might crawl out of the 00's and into the current decade lol

I liked the comment that if you have a symmetric ball and no wt. hole,bring your spare ball. I have 2 symmetric balls in the bag,no wt.hole and have zero carry issues with them what so ever. I think Mo is a very smart business man who makes it sound like reinventing the wheel. On the other hand there were parts of his presentation that were very informative so you kinda have to read between the lines.

Exactly.  Years ago under Morich Mo said they only make asymmetric bowling balls because that's all you need for today's oils and conditions.  Then magically everything changed and he started using one of Brunswick symmetric cores on his equipment because things changed again and bowlers needed symmetric cores.  Change being sales.

You have to figure out what is informative and what is "sales".

What I also found somewhat contradictive is Mo's comment on how you have to come around the ball for hook and higher tilt is best. He's been preaching that for awhile. I thought the point of asymm's is you program the reaction with the ball/layout for the release used and  up the backer's need a short val angle. I found asymm's don't like release changes where that's the advantage of symmetrical.

Now I do know bowler's that can't come around the ball to save their lives and other's that spin the crap out of it so you have to not fall for the sales pitch but one thing Mo said I do agree with is the sky is not falling.

Spare ball comment was also made in reference to pin down vs pin up layouts.  Take it for what you will.  Especially when for the comparison he uses a 3.75" pin up vs a 5" pin down.  Apples to not apples

Don't get me wrong as I'm not a Mo basher. I think he is a very polarizing figure in the bowling world and a wizard with core dynamics but in the end it's all business. More power to him but I'm a skeptic and I have to be in order to try to make the best decisions for my game.
the other issue I have is most pro shops will not offer to figure all that is needed for the bowler unless they spend 500 bucks for a ball. most bowler's will migrate to the cheaper shops who will just slap holes in a ball and send you on you're way. So the good shops file for bankruptcy and the cheap shops make a killing. Sure you can work harder for free but you won't keep up. So now it really becomes up to the bowler to figure out what really works for them.
