Go the HBF bifocals. It will be a while before you won't be able to focus closeup and the instruments with the reading bit. Don't forget: if you need them for your licence, you need two pairs.
(I did try progressives and gave them a miss after a short time; I can see their advantage when you get to ACMS' position of needing 30cm (charts), 74cm (panel) and outside focus ranges).
