any bridge is sufficient to the task... none can GUARANTEE superior tone over that from any other... Superior is a measure of your preference only, in this case the sound of one bridges sound over that of another.... a 30.00 "no name" has every bit as much chance of pleasing you as does a 200.00 over promoted piece....
fact is the one that's on there now may well sound better to your ears than whatever you decide to replace it with, if you can listen without any prejudices...
I would strongly advise you against using the Wudtone 'Holy Grail' tremolo bridge, Wudtone the company, and it's owner Andy are very very bad to try and do business with, you will wait months for the bridge while constantly getting emails from Andy telling you how he has the bridge that you have ordered off of him - for considerably more than what a complete Callaham bridge costs, in his hands right now ready to be shipped out to you, and he will string you along for months like this making you wait for a bridge that he has supposedly got in his hands ready to ship out to you.
There are lots of good trems available. The callaham is popular because it looks, feels, and sounds basically vintage, but with a few refinements and very good build quality. There are plenty of alternatives that do just as well.
That said, the gotoh bridges are all very well made and very reasonably priced. The 510 models with bent saddles and steel block work really nice, sound fine, and have a tension screw for the arm.
As others have said, very decent other trems are available. If, (as I guess) you are looking for a vintage style, I'd suggest one of then higher-end Gotoh's, but with a Highwood saddle upgrade that you will needs to get from Highwood. They are 'vintage looking', but designed so the grub screws don't to poke into your hand.
I had them on a Callaham and found them excellent.
If you are prepared to go more 'modern', I'd suggest MannMade USA and you wouldn't have to bother with getting Highwood saddles.
I recently picked up a ABM 5050 Strat trem and also put a set of Highwood Guitar Parts saddles on it. The ABM is every bit as good as a Callaham, plus it has an arm tension set screw so you can adjust how loose or tight you want the arm. I love the Highwood saddles, I've used them on various trems like Hipshot, Gotoh and Callaham, an excellent upgrade.
I recently replaced an American Vintage trem with the appropriate Callaham. Untremed? I heard no difference. When using the trem, The Callaham is "silkier". I know that sounds weird, but that's what it feels like. There is no zero spot, the smallest movement is transferred to the strings.
I've loved every piece of Gotoh hardware I've ever bought, most recent being a VSVG trem. Great action, no play in the arm, and super comfortable bent saddles that form a nice big flat surface under the hand. Suhr uses the 510s (or some version of them) stock. I think anything with a bushing for the arm to fit into is a massive improvement.
AFAIK the V Trem only comes in 2 1/8" spacing, but it's a killer trem, and with the aluminum block, super light.
If the vintage 2 7/32" spacing is important, the Gotoh is really good. If having the string balls at the bottom of the block is important, get a Kluson steel or aluminum block, they're great.
Maybe a Kluson trem? If the saddles and plates are of the same quality as the blocks, they should be very good.
Raw Vintage saddles and springs are the best IMHO, the springs are softer like the vintage ones, and it does make a difference in how the trem feels.
