Fair enough. As a mechanic; automotive, heavy duty and instrumentation, I had been taught in trade school that hydraulic cams did not have takeup ramps as they are not necessary. Appears as you stated that they are used, but of lesser dimension than on solid lifter cams.
Even so, I would be highly reluctant to use solid lifters on a hydraulic lifter cam. That is a personal choice and what others choose is totally their choice.
