in using 70% alcohol and i mix it in a 32oz bottle with distilled water i put 10oz of alcohol and the rest with water is it better to use more or less alcohol mix with water?

I would use a little less, at that dilution you're ending up with a roughly 21-22% alcohol solution which is on the strong side. Personally I'd try to go with about 8oz and the rest distilled water which should put you into the 17-18% range. That's where I personally mix to with good results although depending on what film you're using it may still be a little strong, if I remember correctly suntek doesn't recommend more than 10% as an example.
