So I want to change from 9s to either 10s or 11s, I have a strat with a 2 point floating tremolo. At the moment has 2 springs in the back...

Just wondering if I would have to make any adjustments for either of the changes, and whether or not it would be too complicated for anybody who hasnt done anything of the sort before. I have some spare springs and it looks like it would be easy to put an extra one in if needed, but would i have to do anything other than that?
You might have to tighter the screws in the back but I wouldn't have thought it would be neccessary to put another spring in the back.

My black strat is set up is for 10's
I use three trem springs and my set up is flawless for Blues rock
