"Silent" piston heads reduce impact force, therefore are very good to have and not actually very silent at all.
For high ROF, it's a good idea to lower your muzzle velocity to 350 fps, that alone will increase your ROF as well as increase the life of your gearbox shell.

Hmm odd TM Internals are actually of good quality especially the piston itself.
Bearing bushings on anything over 350fps isnt a good idea as they can and will sieze up. You want full metal bushings.
Silent piston head yes does reduce impact but also lowers FPS.
I have yet to see a Ver.3 mechbox blow from 400fps upgrades. hell even 420fps with just the spring, bushings, and spring guide replaced it has not broke yet and the person dry fires it like hes in a warzone.
