I only put them on if the string pops out of the nut as you have already mentioned.On my new Warmoth CBS neck, I have gold played brass roller string trees, but I haven't installed them yet.
On my Fender replacement neck, that I was using previously, the b& e strings would jump out of the nut when I would do a back pick in open E, so I added roller trees.
On this neck, with Gotoh SD-91 Vintage Tuners, I'm not sure I need them.
Thoughts???
