Whenever faced with this quandary, (which isn't often!), I take a good look at extreme spread. Any one-time small group may look great that day, but not every day (especially if you shot these loads in brutally cold weather). If you have one or two loads with an extreme spread of 7-14 fps, and another with a E.S. of 65-75 fps, I'd concentrate on the first two. They show a higher potential for an accurate load day in and day out.
