Just replace my Mexican Strat bridge with this one and not only it's a great fit but also a great improvement (please check also other reviews since I also share most of their opinions). It was only 30gr more and some larger springs, but it makes a lot of diference. Probably material is also something to take in consideration.
Pros: Good quality and several spare parts. Fits well and it's easy to replace. Price is acceptable for this kind of quality.
Cons: Doesn't bring any instructions or installation manual. It would be nice to have, specially for the ones that would like to do it by their self. Why not one link? ... I couldn't find anything related in the internet or even in their own site. Torpedo buttons comes in white and black. If you need cream or vintage style, you need to drop that white button in your coffee for a couple of hours. ;)
