great concept Badger,, I always thought I would just make bows and mark them ,, and if they suited someone great,,,I always get tempted to use the scale to hit a weight,, but really more efficient if you make the bow till it is tillered and stop,, what a nice concept,,, I dont practice like I used to ,, so cant pull the weight I used to as well,,, african drumming keeps me tuned up a bit,,but making and shooting bows is the best practice,,, especially like you said when you are exercising the bow by hand,, you get more exercise than you think ,, which is great,,good luck on your shoots,, keep up the good work and you will pull the weight you need, we just have to work a bit harder as we get a bit older
