Re: snapped the truss rod.
If your original neck has the traditional Fender profile (nicely rounded 'C') and you consider a replacement unit, be aware that many necks, including most modern Fender necks, now use what is called the 'modern C' profile, which is somewhat flattened along the centreline at the back, and they give a different feel. A feel which, whilst being comfortable and allowing easy transitioning between various types of guitars, is not the traditional Fender feel.
I could feel this on a couple of my Strats, but i double-checked by buying one of those contour gauges from the local hardware store for about $10 and comparing several Strat neck profiles at various parts along the length of the back of the neck.
Warmoth's modern C doesn't have enough wood to re-shape the profile, you'd need to get one of their bigger profiles. Actually i think their '59' profile would be closer, although it would also be thicker (meaning it could probably be slimmed down to some degree if you wished).
