I use them when hog hunting with my trad bows. These and the original grizzly sticks are the only shafts that I have gotten complete in the dirt penatration on pigs/hogs. The new ones are far more consistant lot to lot than the original. Have not broken one yet. I don't normally shoot them when I expect a past 20 yd shot cause they are quiet heavy. My regular arrows shoot 189 fps and the momentoums about 141fps. I notice know difference to about 18 yds then they really drop out. Ive never shot a pig past 15 yards and most inside 10. It's really thick where I hunt.
Just my opinion having actually shot and hunted and killed game with these arrows in question.
