I guess tha'll be the APII or the Seth Lover... You could also consider the 59 neck to have a vintage alnico V humbucker set with a mached tone. But the 59 it isn't as warm or buttery as the AP-II or the Seth.
I dont know if I would consider the pearly gates or the 59 buttery and warm. The Alnico II pro and Seth Lover are buttery and warm though. Go with one of those two.
