Zinc is a great, balanced material for tremolo blocks that has fallen victim to marketing hype for unnecessary "upgrades".
In terms of its physical structure, zinc alloy is closer to titanium than either brass or steel and actually behaves most similarly to titanium when used as a tremolo block.
Regardless, as long as the block has sufficient mass, the material it's made of makes such a small difference that most players would not be able to tell by ear or feel alone.
Oh, come on, why would they lie to us?
Anyway, as far as FR upgrades go, the tip I see the most is that the Jacksons and Kramers (? I think) all come fitted with licenced (? maybe) FR Specials, and if you're really concerned about making them sound "good" (? they sound fine), you upgrade the saddles to the titanium (? aluminium? osmium? magnesium? Don't look at me, I'm no scientist) ones used in the OFR (? I'm just messing with you with these parentheticals now) and you're good to go.
That said, you don't need to jump the gun and upgrade right away; you've got years before worn-down saddles are even an issue.
It's the blocks that are complete s#!t.
As always, don't take my word for it. I'm not a lawyer, and you won't win if this goes to court.
