Well, paired with the proper cover, let's look at my stuff because #900Global lol
Ordnance pearl. Tall inner core with 2 flip blocks. Core has been in the OMG Pearl, Drift, Rip it, and the Black Mamba. Essentially 2.55 .055 for most of them, rip it being slightly higher RG and lower diff, but you get the point. OMG Pearl was F73 pearl, Black Mamba was F74 solid.
The taller the core, the more it's going to tumble. It's much like the analogy of the figure skater spinning. With their arms out, they spin slow (higher RG) and as they tuck their arms towards their center of gravity, they spin faster (lower rg).
As you put more mass towards the cover of the ball, the less energy it's going to expend early because it's not going to rev hard off your hand. Very much like how you imagine resin to be. Long and snappy. Take the old Morpheus core from the Track Freak line. In particular, the Phenom. I put a 65*5*40 on that ball, and it never read the lane. Ever. Every one of those balls I had to go 45*4.5*65 or stronger to get them to read the lane properly for me. Tall cores with a huge flip block on them. The Xception was my one standout where I went 60*5.5*65 and the thing hooked out of the building because the cover and core matched up so well.
So when balls don't read early, they can float downlane without spending lots of energy reading the pattern, so when a Boost gets downlane without using a lot of energy, when the cover finally sees friction, the core says "Ok, we have all this stored energy, so let's use it all right now to go the direction we're rotating."
So after my long tangent, when paired with the correct cover, tall cores will transition faster than squat cores. Ordinance Solid is the opposite shape of the Pearl, and that's gonna be our benchmark smooth ball.
