I know several of us here on the form have a 7d mark ii now and most of us seem pleased with the amazing AF tracking. So far I am thrilled with this camera's ability to track compared to the old 40d. I have watched plenty of YouTube videos on the AF case settings. I am interested in hearing of what case settings most of you guys are using for BIF as well as general subject tracking, song birds particularly. Mike-AKA lame-duck, I hope you can chime in on this. It looks like you have put plenty of time behind the 7d mark ii. Here is a link to one of Arthur Morris's video regarding this. AF servo case starts @ about 3:45 into video.
