Robert, I certainly understand all the geometry, but doesn’t it all come down to friction? If the nut had 0 friction (impossible to obtain) I’d think the geometry wouldn’t matter. I have 2 Strats with the LSR roller nut, I’m gonna go look at them today. Seems like a good compromise in trying to have prefect geometry.

The roller nuts are decent, but they are only available in 1-11/16" width and 9.5" radius. You can "squeak by" up to 11" radius, bit it's never "right" and generally, the low 'E' and high 'e' is too close to the 1st fret on a flatter radius board.
Additionally, the nut slot on a Warmoth neck is deeper than a Fender (a lot deeper) so you will need to shim the nut (with proprietary 1/8" wide shims) to the correct height.
