Does anyone block there Trem? Pros/Cons?

So i am not much of a trem user. I might use the bar a few times here and there but not all that much. I own mainly all hardtails. I was thinking about having the trem blocked on my new Majesty. I was curious to hear from those who have blocked there trems what your thought are?

Any Pros/Cons to it?
Did you have better tuning stability?
What method did you use? Tremol-no, Wood Block, Other?
Did you fully block it up and down or just half?
Notice any change in sound/sustain?

Thanks Guys!!!
