I have used magnus myself with great results . One great benefit of useing this head is you can shoot it into broadhead targets / 3d targets and then just sharpen it on the arrow and your good to go . I just use a sharping stone like you would use for a knife and sharpen it in a similar manor to how you sharpen your knife . Idid' nt use them last year but year before last I shoot 2 deer and had 2 passthru' s they definately penitrate .
