I think I am going to have to do more studying and research on this topic. I really didn't notice that much difference in this particular experiment. Maybe ISO 400-500 look the best. Thus far I have been satisfied with the AUTO ISO settings on my camera. This is one of the things I plan to study more on..........when I have time :)
