I was thinking about asymetric core in storm ball for a left hander today and wondered if it would work the way it was meant to because it would be backwords.

The image of the core I was looking at was this.

I take it the pieces of the pancake looking part are different and they would be on the opposites sides for a right hander and left hander.

am I missing something or are cores like this a bad choice for a lefty?

Hey thats a good question I would like some input from the guru's on this I had an original X-factor that I never liked and it being such a popular ball I always wondered why.
--------------------
I should just quit bowling, oh wait I already tried that.
Now that I am back and my Saws are sharp again, I am ready to cut some wood.

Maybe the question should be asked this way.

In the typical mass bias ball mass bias is created by having a portion that protrodes on one side of the core when looking from the top.
It is clear to see how the effect for the righty and lefty is the same!

In these XXX balls or the Single X factor or Super charge balls.  A denser disk(blue in this picture) is in one portion of the core and a lighter one at the other side of the core.

Assuming the darker disk in the picture is nearer the grip cneter for the lefty in a pin next to ring drilling and a mass bias on strong side of thumb.  Let's also assume this is the denser disk.

Now take and drill for a righty the same drilling now the denser dark blue disk is nearer the pap??

Gurus???  Storm Gurus??

my understanding is the pin would come straight out the bottom of that core picture. If thats the way it is it would be opposite densities near the grip for left and right handers like luckylefty was explaining. hopefully somebody knows the answer!

I'd like to retract my first post.  It was a poor choice of words said in haste.

The dense "side" of the core is not on the side as it typically appears in the pictures.  

Imagine a ball drilled for a righty with the pin beside the ring finger and the mb right of the thumb.  The core is oriented with the top directly below the pin and asymmetry in the direction of the mb marking.  When you change to a lefty drill all you are doing is rotating both the pin and mb (core asymmetry) to the opposite side of the grip.

Regarding the core in the picture, I honestly don't know whether the pin is at the top or the bottom of the picture.  My assumption would be that it's at the top, but it really doesn't matter for this discussion.  The point is that the cg and mb would be on the right side of the ball in the picture if the blue puck is more dense.  So when you drill the ball stacked, the blue puck is facing you and the silver puck is away from you.  Then you have the same situation as above.  You are simply rotating the pin and mb position relative to the grip when you go from righty to lefty.  The core is still in the same position for both bowlers only rotated slightly.

If we assume that the blue puck is where the mass bias line or mark is made fine.

However, for a righty in a stacked drilling the silver and black pucks(let's assume less dense are in the grip.  For the same drilling for the lefty the silver and black are towards the PAP.

However, another possiblility and this may be the true picture.  Say the black disk is where the mass bias is.

Now on a stacked there is symmetry whether right or left HOWEVER if we assume that the white is the lowest density disk,  black the highest and blue the second densest we again have a disparity.  Lightest density disk for the lefty is towards pap and for the righty we have the second densest disk towards the PAP.  Is this why the righties have the world in my house with their triple xs and we instead on the left just have jumpy with the same ball?

Or is that the oil pattern!
