I've ordered Kirkey Series 71's. Will fab up a mounting system that anchors on the OEM points, which I think means slide-in mounts up front and bolt-in at the back of the seats. If I get it right, I should be able to swap them out in 10 minutes. That means Kirkey's for the track, and OEM for the DD stuff.
Could not see driving around all the time in race seats with 6 point harnesses and roll bar. All my stuff will be removable so that I can get (mostly) back to stock and still take my kids to school
