Yep, Magnus 2 blade 125gr Stingers for me and my 56# Longbow as well......they fly great and are as sharp out of the package as it gets. Not terribly expensive either (lifetime warranty too if you crack one up)
I trust them 100% from my longbow.

I am shooting a variety of heads out of my bows based upon the energy they put out. I will use the Magnus Snuffer 3 blades from my Black Widow because its cranking them out with the 62# draw weight and can handle the extra blade and diameter. I don't quite trust them from the longbowwhich is a little lighter in the energy department and decided early on I wanted to shoot a good 2 blade.

I would also shoot my 220gr Muzzy Phantoms from both if I wanted to up the arrow weight a bit but I'd shoot it as a 4 blade from the recurve and a 2 blade from the longbow again based upon the actual energy output and the different configurations just being a slightly better compliment to each.

I have a few others but those will be the game time heads for this season.
