Well, I think what you are talking about is Tung oiled finish on the back of the neck. I had a Carvin bass with this, and it felt very good playing, but man, did it get dirty!
I haven't heard of an Alembic with a oiled neck, but satin finish is supposed to be very comfortable too (I am getting one on my Excel Experiment).
Gloss is okay, but if you sweat alot (I do!) then it's not uncommon to get your hand stuck while playing.
