Adding more tension on a MadCatz TE Round2 Stick Combine Springs?

I was watching this video

" Sanwa JLF Ultimate Mod WITH UPDATE! "

and I dont want to go through the complete mod, But i noticed he combined a Seimitsu LS-33 Spring to the stock Spring , does that add tension? or whats recommended?

My current fightstick is extremely loose and moves with no pressure at all

would You recommend I just go for the spring or if you know any other mods, or just replace the whole Part?

Buy the springs and add to the one you have now.

I’d rather just use one ls-32 spring as opposed to combining two, much cleaner and more reliable. In the meantime you can stretch out the current spring about 3/4 an inch and that should temporarily give the spring more tension.
