I used the Wasp Boss SSTs last year and thought they were great. However, they don't hold a candle to the NAP Nitrons. They are IMHO, the best broadhead ever made. The blades are the sharpest I've ever seen on any broadhead, and the weight tolerances among the 6 Nitrons I bought are INCREDIBLE - there was only 1/10th of a grain difference - all weighed between 100.2 and 100.3 grains. If you don't think that means much, weigh 6 of your favorite 100 grain heads sometime and see if they even weigh near 100 grains. And oh yeah, they hit right with the field points out to 50 yds.
