I'll ask what he is going to use but I believe hide glue is a big contributing factor with early Hofner neck joint failures. I think a modern glue like Franklin's Tite Bond is a much better choice.
Hide glue is what enables the neck reset. You warm it up and it melts and the neck is off the bass, clean and simple. Then the planes are smoothed and the angle determined, and then it's re-glued.
Using Tite Bond is like using super-glue instead of the 4 bolts in a Fender: it will hold, but you will never detach the neck again without major surgery.
Hofner glued-in necks were designed to be held in place with hide glue. And yes, they may need a neck reset every decade or two, just like Fenders need shimming once in a while. I've seen the damage done when other glues are used in Hofner neck joints. It's a lot of work when it's time for the next neck reset. It's still doable, but costs more to repair.
Hide glue isn't weaker than other glues. It just melts easily when warm, to allow easy and clean neck removal. Hide glue is what holds upright bass necks in place, and the string pull there is more than double the pull on a bass guitar.
