Man, I have learneda ton.....scent control is what I consider to be the most important..Being upwind from a deer at 30 yds for 30 min and not getting busted, that was priceless. among others are stand placement, arrow building, 3" groups at 25 yds with a rest that has some minor contact with the vanes (that is my next thing to learn, to tune my own bow, I had this rest installed at the local shop, need 1/4"more vane clearance for perfection) I do not take shots longer than 25 yds by the way! Need to learn more about rattling and calling.
