What differences should be noted?
« on: February 16, 2018, 08:33:18 AM »
All things considered equal - Say I take a strong Asym like an Alpha Crux with my go to layout on asym's being 50 x 4.25" x 30.  Now I take another one with 55 x 4.5" x 50.

What differences in motion should I see?

In theory, the ball will have a longer hook phase.

In practice, you won’t SEE the difference at all. The balls will roll so close to the same that you won’t be able to tell them apart without surface changes. They’ll work on the exact same conditions.

If you take that VAL angle to 70, there might be a big enough difference for a perceptible change in ball motion. In my experience, even with that big of a change the balls will still overlap on oil volume, but the shape may change enough to fine tune carry. Core shape will play a role in this though, especially in a case like the Crux core that was designed to maintain the reaction shape to make it drilled friendly.

Thanks - still developing my knowledge on asym layouts.

Intrigued by Mo's suggestion that 50 x 4.5" x 40 w/ P3 Hole is Length w/ Strong Finish and that 70 x 5" x75 is Length w/ Control. Looks like both keep the RG close but significant change in Diff with the first being the high. What's the middle ground here as in which variable should get modified first to try and meet in the middle?

Still pretty layout dumb but lower drilling angle generally means quicker transition from skid to hook.  Smaller val angle generally means quicker transition from hook to roll (sorry if being Captain Obvious).  Also important is the ratio between the two angles.  With my style I really need the hook phase as long as possible so I shoot for 1:2 to 1:3 on the ratio.  The opposite would be true for someone who has problems getting the ball down the lane.  As for pin to pap on an asym will put in next post a guide but because its copyright will delete in a day or two.
Kind of noob when made this account so take advice with grain of salt.

For asymmetric pin to pap values.

My experience with layouts has been its far too easy to stress over little things that hardly matter.  Unless you are incredibly consistent with everything especially release its very easy for changes you think are major to disappear in the noise.  Really is more a fine tuning thing for most part.  I worry a lot more about surface but then again not quite at the fine tuning stage either (ie. getting to pocket consistently more important than specific board it rolls off in the back).  Even pin to pap distance which is more important with symmetrics doesn't matter as much as one would think as shown below.

Syms are easy.  Not much to them. Asyms being more dynamic is where I'm focusing on.

More lecturing myself I guess as I am sure you know a lot more than me sorry.  Here is a good guide with some examples from Mo.
