The 160 will be Tungsten and the 64 could be T or daylight.
For examples of 160T check out the Vancouver shots in my gallery. The film acts very much like a traditional neg film when crossed. I rate it at 100. It is fairly flat when crossed and is best when used in higher contrast settings.
If the 64 is daylight balanced it is very contrasty and will have strong Blue/Yellow cross over -- Blue shadows and yellow highlights. It has very limited tonal range which makes it good for turning low or medium contrast setting into dramatic high contrast images. I would rate it at 64.
I would also recommend bracketing toward over exposure. This will be especially beneficial if the film is out dated and suffers from lose of DMax. I had a ton of the daylight 64 that was out of date. It required a good deal of over exposure and had a very strong yellow cast. The exposure latitude of the 160 will be greater than the 64.
If the film is new the 64 can be over exposed and under developed (1-2 stops over exposed, pulled 1-1.5 when developed). This will help manage the contrast and make for a more printable 'neg.'
