RE: Paper tuning?
I know its off topic, but I use paper tuning for my trad bows quite a bit. Just for "blank bale shooting". it will tell you a lot about your release, and form.
Another good use of paper tune is culling out arrows. (yes, I learned this off of Len) Lets say I have bow bare shaft tuned, broadhead tuned, and want to go thru my arrows and find spine inconsistencies or fletch orientation. Paper tune is great for this. Unless you want to BH tune or bare shaft tune them all.
I think its an ok (get you in the ball park tool). But the proof is in the pudding for a hunter. And when the moment happens for a shot you want to know where that arrow is going. And thats with BH's.
