Default Stronger springs in Futaba 4GRS

Running a Futaba 4GRS stick radio. Lovely radio, but it could have a stiffer spring setup. I've adjusted the spring tension up to the max tension inside the transmitter, but after using my friends SANWA Exzes, that has some very strong springs which I liked a lot. All I've found in googling around is replacement springs, no optional ones. Could you shorten the standard springs to increase the tension? I'm also wary that a stronger spring could cause the mounting point to fail, but I really like the strong feedback feel with the SANWA setup.

Any advice from the Stick Radio Mafia? No, I'm not buying a SANWA

Default Stick spring

Been using futaba 4grs for years now and never changed anything other than 7-3 for smoother throttle control.
You got me thinking about spring stiffness thou.
I am sure you could cut a coil off the existing spring or something.

I thought about trimming a few coils off the springs, but I think I'll wait and get an extra set to hack away on. Now I just have to find the part number, then find someone who stocks Futaba springs for old transmitters. Should be super easy
