I think paper tuning is ok for aluminum because they don't flex as much as wood or carbon. I have paper tuned 2018s through a modern day recurve cut to center. But because of the shooters paradox it is not a good way of tuning arrows through other types of bows. I was able to, with a good release, "bullet hole" my arrows at 5ft. and at 15ft. But I usually rely on bare shafting.
