1. IF 2 totally different shaped cores (companies not important) say 1 a taller thinner core and a shorter wider core both have the SAME RG, and SAME differential
will they roll the same? In theory i would think they would.
Both having same covers as well.

i ask because it seems alot of the companies seem to stick with 1 mainline core which never ever seen to change year after year...lane# basic diamond, Storms eraser core...columbias rock on core....v2's and they all seem very similar and seem to be proven.
Where the hi end cores seem to be way more exotic and change alot more drasticlly from year to year
