I’ve gotta jump in here with my vote against a gloss finish on that beautiful slab. Don’t think that Nakashima would use gloss either. I agree with Clint about leaving the characteristics, and I think that you are wise to leave off the stain. I kinda like the contrast between the sap and heart.
BLO and then a nice satin wiped poly rubbed and waxed would be my choice. BUT it is your wood and your choice. Or your other option is to send the slab to me (didja see the smilie face).
