oh rip, wait for christmas Anyway, I can give you some advice considering guitars with this type of bridge
From my experience, Jacksons are great, even the one that costed like ~400€, made specifically for metal and soloing
Also, don't lose those lockers you put on the nut, or else youg guitar will get out of tune *everytime* you use the trem
I guess you don't buy cheap guitars, and now I do think that you should give money if you want quality, and try the guitar before you buy it
Also, very important, if a string breaks, you are totally screwed, especcially if it is floating, the other strings will get completely out of tune, the action will become lower, the frets will buzz etc, change them immediately
