Gummy/soft is preferred because my thumb digs in enough to mimic flatness.Fission Volts are "gummy".
The flattest Volts i have had are all Neutron....(not cosmic)
In my experience the Proton plastics in the overmolds (axiom and mvp) are the more understable. Neutron are more OS....especially in Cosmic.
Fission seems hit and miss(stability wise)
Plasma seems hit and miss(stability wise)
Kind of a reverse of stability compared to other companies plastics. I only played around with gyro for a year , but this was my experience across the board with all the molds i tried.
