I would have to say Campag, tho looking at the frame, the angles are quite relaxed; i have a couple of steel framed Italian bikes and you can barely get a finger between the tyre and seat tube...
If you can find a nice Campy triple ( see my de Rosa AL+ in reader's bikes ) that will get you up anything, tho' i ride in the Cotswolds and Devon ( V V hilly! ) on 53/39 11-27T ( Cervelo) and even 52/39 13-23T on the oldies...
I have small hands and find the new Campag levers perfect, the fulcrum pin placement on Shimano STIs meant I had too far to reach, even with the rubber shim.
On the oldies i favour Shimano levers ( Dura Ace SLR ) they are light and sprung and modulate perfectly for me; ( the Record levers I find too clunky and struggle to shave off speed on fast decents with delta calipers... they go squeak squeak squeeeeel....hedge
