Hey BR Fam!

My stats, before I dig into my message:

• PAP is 5.25 over and 3/8 up
• 330rpm
• 16-17mph
• 30*-35* axis tilt
• 50*-60* axis rotation

Lately, I've been really digging asymmetric cores, both highly and slightly asymmetric. Over the years, I've noticed that I succeed highly with a few different VAL angles, and struggle mightily with others.

I succeed with VAL angles that are usually between 30* and 40* with 5"+ pin to pap distances. These balls for me tend to clear the heads well and shape very nicely in the back. The closer to 30 (or even 20 if I want), the sharper the shape.

I also succeed with VAL angles that are usually between 60* and 75* with ~3-4" pin to pap distances. These generally put the MB on (or beyond) my VAL, and the ball has a smooth adn VERY continuous shape. It's wonderful when I need some oomph playing straighter angles.

Recently, I tried something a little different: 60* x 5.25 x 45* on a 900 Global Flux. The ball responds surprisingly quickly to the friction. I expected it to be a bit smoother than say a 20* VAL angle. However, this ball wants to stands up immediately after seeing any friction.

What do you think is causing this ball to be really sensitive to friction?
Would giving the ball some teeth (say 2k or 1500 sanded) help smooth out the hook phase?

Thank you all in advance for any help! It's great appreciated.

My belief is that at 45 degrees, that is when the core is at its most unstable.  My belief also is that when you take the 2 angles and add them together; closer to 10 total would give you the most length and the closer to 180 total would give you the earliest and smoothest reaction.  When you get close to 90 total; that is when the core is most aggressive.  So the 5.25 pin would give you the push through the front part of the lane but the total of 105 is close enough to 90 to make the reaction pretty aggressive. 

You are also using a ball that has a core designed for length and angularity.  2.55 RG will help create length and the .048 diff will aid in an aggressive backend motion.  The ball comes out of box at 4000. If you want to tame down the reaction somewhat you could step down to 2000.  That should help a little bit.  But bear in mind that asymmetricals are already aggressive in the midlane as it is.  Sanding too far will burn off energy too quickly and make the ball roll out and hit pretty weak when it enters the pins. But start at 2000 and go from there.

Well, you also put the pin at 5.5 inches, which will make it stand up harder than the 4.5 inch pin.
