If you follow through on a neck pickup, just have the cavity there and say “fuck you, you fill the damn thing. Picking the bridge was exhausting”

Lollar, low wind, unpotted. Perfect for the basement rockers here playing 4ft away from enough gain to serve with pancakes, who, also want to add the joyous overtones of close proximity to an attenuator.
Pickup choices are so personal to someone’s style of music and what amp’s they’re using. I would just err on picking something kind of common and inexpensive. Someone is bound to change whatever is in there. Or pick one you’ve always been curious about for yourself, so you can at least hear it through your gear before sending the guitar out.
It’s almost a shame you can’t wait for the lucky recipient to be known and then they can choose from a high output choice and a low/medium output choice. You could call it the Rock option or the Roll option. Or the Punk and the Poseur option.
Just between you and me, if you feel really strongly about one Hum, especially if you do decide to do a finish that wants that real estate, pull an executive order on it.
