Then the top end of a flat tappet hydraulic rolls off at a lower peak rpm and are usually limited to 6500 rpm as far as making good power.
the lobes are more aggressive in a solid lobe and even more aggressive with a roller.

mid range power say 2k - 5500 is about the same with a hydraulic flat tappet and an equal solid

the solid just has a little more on the bottom and a little more on top.

hydraulic cams work good enough for 75% of the people

I agree
