First, in response to the previous opinion, it is quite normal that the vibrato dislocated his pivotal if we relax the strings, or no-no Tremol
The no-no Tremol facilitates change that string after string.
If you break one, the others are awarded.

There is only one way on a floyd rose all the strings to change or remove the vibrato: get in floating mode, relax all the strings until the vibrato partner back to touch the heel on the body.
And remove a spring and again until you remove the last resort.

These two problems are not problems with the Tremol-no, but problems with any floyd rose.
A floating tremolo is floating ....
Similarly, in "dive" mode (Tremol-no, block or otherwise), if you relax too much string vibrato dislocated ... becaufe the spring shoot.

on the other hand, in fact if you want to stay in "dive mode" only, I recommend any one trem blocker or even a piece of wood stuck behind the heel: it's cheap and even Van Halen does

It is becaufe the floyd roses are wounds that have invented things like the way "dive" or Tremol-no
There is also the trem setter, but that is just an improvement in stability.
