Adjustable rockers adjusters problem?..

Beehives also have a dynamic resonance frequency due to the way the mass distributes as it compresses. This can be a major benefit that can result in lower spring pressures before the valvetrain goes unstable. Plus a reduction in the reciprocating mass.

But none of that fixes bad starting geometry which needs to be corrected for valve length and total actual lift.

I would also just "guess" that between one or the other, correcting rocker geometry has a much advantage than just adding beehive sprAngs.
