I left Friday, it was raining...
I needed seriously to be light, so just 2 lenses, the 180 to take details of Trajan and Marcus Aurelius columns.
Thought seriously to bring the 300/4.5 ED non-IF instead of the 180, but the weight/size was too much.
And yes, I had headaches one week before the trip, trying combos of 2 or 3 lenses, and testing some against the 42.2 MP Sony sensor: shocked to see how - at this resolution - the 180/2.8 is visibly better than the 200/4 ai-s.
