the problem with rotating the armboard is that the arm is mounted on an eccentric. i had the same set-up for a while. rotating the armboard changed the P2S distance. i ended up using a P2S of 255 and adjustung the cart forward in the headshell to align at that P2S using the feikhert.
if i had this issue again, i would have a look at what atmasphere said above. i wasn't aware of that screw. as you mentioned, maybe the combination of rotating the arm in it's base and rotating the armboard will maintain the spec'd P2S. i don't fret over the P2S, it's a starting point. as long as you align properly with the baerwald or loefgren scale, that's what the slots in the headshell are there for.
