408 hyd roller, too much spring pressure?

Are you calling dual conical springs beehives? I don’t.
It's a matter of semantics. We are talking about the concept of the beehive/conical design and their advantages in relation to retainer weight and harmonics. You seem to be very narrowly focussed on a few niche areas that do not necessarily apply to the average guy on the street – likely including the OP of this thread, who appears to have a very similar build to my own.

Horses for courses. Blanket statements about springs or anything else are just that.
