After a LOT of mulling (and a lot of keeping my fridge open for many minutes at a time staring at film), I've decided what to bring to Europe.
1. I will bring 2 cameras. The XA, loaded mostly with Tri-X, and the Canonet, loaded mostly with various color film (see #4).
2. It looks like I'll be spending a good 2-2.5 weeks in the frozen north (Scotland, England, Scandinavia), so I'll need pretty fast film up there. Then 1-1.5 weeks south of the Swiss-Italian border, so I can probably get away with slower film there, but I think no less than 50ASA.
3. Based on my last Eurotour, looks like I shot 7 rolls of film in my XA and 4 rolls of film in my Canonet. That was a 2/2.5-week tour, this is a 4-week tour. Double everything.
4. THEREFORE. One brick of Tri-X. Should roughly last the whole trip in my XA. Then, the following for the Canonet:
1x Fuji 500T @800 (the last of my coveted stash from jharr) - to be used in Scotland
1x Agfa Vista 400 (the last of my coveted stash from Volker) - to be used in Scotland/England
1x Ferrania 200 - to be used in England/Scandinavia
1x Elitechrome 400 (@200) - to be used in Scandinavia
1x Elitechrome 100 (@50) - to be used in Germany
2x Ektachrome 100HC (@50) - to be used in Italy and Spain
Let's see how this goes
The basic plan is to use the 500T in Scotland and the 100HC in Spain, everything else will be modified to fit
