Fender Roller Nut LSR

The incontestable winner in the harsh nut game (vibrato category).
Expensive but its excellent quality justifies it.
Useful fitting accessories.
Contrary to some user's advices, the installation of this technological marvel
is rather easy (if you are cautious and skilled enough) because you don't have to worry about the notches. I customized one Stratocaster and one Les Paul (w-Bigsby) with this nut.
The result is bluffing: perfect alignment, frictionless action, discrete but great look.
This roller nut permits you to engage safely in the most aggressive post-Hendrixian vibrato playing.

Installing it requires some permanent modification of the fretboard BUT the versatility that this nut brings to a guitar (ability of using different string gauges without having to change the nut) along with the fact that it is a similar material to the frets and the saddles makes it worth the effort.

The fact that you have to enlarge the nut channel towards the bridge end makes this mod quite permanent.

Pros:
- Changing string gauges without requiring a new nut job
- Frets, nut, and bridge saddles all made of the same material, less tone difference between open notes and fretted notes

Cons:
- Requires modification of the nut slot in a very hard to undo way

I had a Strat plus that had the old Wilkinson roller nut. The nut was good but trying to squeeze 10s into it was a drag. I tried this out and it was a very easy replacement. I prefer these roller nuts than the bone bits.
Make sure you use the right drill size when fitting it. The little screws can break and it’s no fun gettin em out.
The price ain’t bad, sure a normal synthetic bone is cheaper but you have no tuning issues with these. Also, your Strat plus will like this better.
You only have to drill 2 holes, you get the plastic adapter with it to make the replacement a breeze
