I recommend Porta 160 and 800 in 120. Although best if kept refrigerated Porta can held at room temps for a couple of weeks without much issue. For 35mm I recommend Kodak Gold 200 and 400, they do really well at room temperatures. I just tired a roll of Cine Still 50 and 800 tungston, very sharp, colors not overly saturated, the 50 is a little on the contrasty side. For a 3rd camera, if you can fine one a good all weather point and shoot like a Minolta Weathermatic or my Fav Pentax IQ zoom WR. Not small, but there are thunderstroms this time of the year on the rim. To travel light, take a WR point and shoot, light wt tripod, Gold 200.
