Just to add a bit of personal experience, I am in the crowd of shot placement. I am going to call myself out on this hunt but three years ago, I blew an easy shot at 10 yards. I hit a large doe in the shoulder blade with my 70lb Bowtech using 100gr G5's (I still use them BTW). She ran off with about three inches of the arrow in her shoulder, two days looking for her with no luck. I was heart broken, still kick myself for blowing that shot. Just goes to show, if you make a bad shot, you will get poor results. Use what you are confident in. That is a big part of hunting. Having confidence in your abilities and equipment. In the end, it's about giving respect to the animal by doing everything in your ability to end the chase quickly. I say go with your expandables. That's what you know and have confidence in.
