These are supposed to give a different sound profile?
No. ThicThock is just the “brand”.
@ajoflo - Thanks for this! Have you tried the MP (progressive) springs?
4 springs are offered: two linears (at some what unique weights) and 2 progressive springs. I am curious about the progressive springs since these function by having a light initial push but get heavier the closer you get to bottoming out. They essentially “push back” more preventing you (ideally) from bottoming out. @skepp
Ye, I ordered 3 different kinds from sprit the other day. Gonna be fun to try.
