If i remember correctly, #60 looked to be a pretty nice campsite. It was nice and open and appeared to have room for quite a few campers. If it was me, i would stay at #57 just because i would assume the fishing would be better since there is less fishing pressure. If you can fish the bend then i would, gotta be some good fishing back there, just be careful since it gets away from the trail.
If you and your wife can handle the extra mileage i would definitely stay at 57, alot of history there and a nice campsite. If you have any more questions just let me know.
