Yu have a decent enough series with these latest shpots Jim but the main problem is the tendency to lose shadow and highlight detail due the high ISO setting. I can appreciate the relationship of aperture and shutter speed with the lighting conditions, so perhaps you need, if you really must use such a high ISO rating, to change the processing procedure. I don't have the RAW programme for your Canon 60D files - except I think my Lightroom may have such a facility. Can you post the RAW files of say the first two in this series so that I can see what is perhaps possible - meaning to upload to Dropbox where all other files are stored and then send me an e-mail when available. However, I will probably not be able to do anything for a while as I leave for the Meet on Friday morning.
