Roger, I kinda disagree, I think a magnus is a excellent head but personally, and its a personal thing, I perfer A zwickey delta over a magnus 1, there is what a 1/8 width diffrence? I feel a Zwickey has a better steel hardness, they are still easy to sharpen but hold a edge better than the magnus I have used. A Zwickey 4 blade you can use a full taper cedar or adapter where a Magnus you have to go with a short adapter or taper, weakening the head and not acheiving trueness in mounting as easy. I have curled many a magnus tip and even had a hole head curl using a short adapter.But I have also curled the tip on a few zwickeys, just seems easier to curl a magnus tip. I know Magnus recently went with a chisled point which should help this. But If I shoot a delta on aluminum I use a long solid adapter and get a 175 grain head. And yes, I would like to see something in the area of a 160 or so Zwickey, I would switch to this head.
