I love my NAP 4000 drop away- I stack darts consistently- I always get fletching contact on my right prong- I've spun the nock every way and nothing seems to help. Field points seem okay but the broadheads can get a little whippy. Someone save the day- I'm staying with NAP because I love the company and their products. I shoot a Custom McPhearson target bow and Bowtech Old Glory- at 70# with Easton 340s, 100 grns.
