Why would you want to use any Turpentine or cross of it here in CA?
Nematode resistance is a very big reason, high vigor, high productivity, and high uniformity between seedlings.
Nematode resistance is admittedly more important for those with lighter soils, which are prevalent in several regions. That said, mangoes tend towards deeply anchored roots, and many areas of CA have deep, loamy soil, so it may or not be an issue for all, but I certainly would seek out rootstock with greater nematode resistance.
