Hey,
Maybe it's too late and you have already begun the testing, but I think that it would be worthwhile to add the winner from the previous shootout to your comparison (BK Precision 2709B). That way, you are in essence comparing 11 meters (assuming that in this shootout, you would test 5 new meters and the winner from the last shootout). This seems like it would provide a good reference. You know?
