Subject: [CR]significance of variations in c-record brake lever "leverage plates"

so i just eyeballed a couple different sets of "c-record" brake levers and i saw a difference in the design of the little metal "leverage plates" for aero cable routing.  these are from the non-variable leverage levers.

variant #1 - i'll call it the "flat-groove" plate.  it's basically flat w ith a groove down the center where the cable goes. 

variant #2 - i'll call it the "v-groove" plate.  the plate has a pronounc ed V shape, and down the center of this V is the groove for the cable. 

seems to me the flat vs. V would have an impact on the cable-pull and lever age.  i'm curious if there is a meaningful difference in how these insert swork, whether there is an "ideal" campy brake caliper which they're supposed to work with.  maybe one is "better" for c-record deltas or croc e d'aune deltas or cobaltos or something else.
