never tryed the muzzy;s but have used the wasp heads for years.shot the sst hammers,and shot the jak-hammer yea they fly as good as a field point but they did not perform as good as i like and i had several friends shooting them with the same results. as far as broadside shots they make big holes. on quarting away shots that was a different story. on two deer i shot they pealed down the side of the deer till they finally caught a rib and only pentrated half the arrow. it did kill the deer but the arrow was still in the deer with the guts draged out of it . hard to belive at 76 lbs @ 10 yards shot. my friends had the same encounter and lost a couple deer. switched to the new sst boss last year flyes as good as afield point and it goes right throught those bad shots that you sometimes have to take.
