Let us know how it goes. Still trying to get a handle on these new TX springs without buying a whole lot.
The 55 G long are heavier in the actuation stage than the 55 G short. This makes it potentially function better with heavier tactiles like the U4 stem, instead of 55 G short. But it's a higher initial press.
I have some test Ergo Clears with 60 G TX (s) and they were a bit light. I was thinking of going to 62 G (s), but wondered about the L variant. If it's comparable to Gateron Yellow, I'm not sure I'd like it, as I found Gateron Yellow to be a bit stiff / sluggish.
