Because you are shooting lower poundage (and there is nothing wrong with that, just something to take into consideration), its better to have a longer broadhead with fewer blades. That Magnus Stinger is just that sort of design. Good and sharp, and with a little tuning should fly nicely off your bow. The Montecs would be a good choice as well, but you are going to have to sharpen them up a bit right out of the package. The Hellrazors are the sharpest of the three "one piece steel triangles" and the Snuffers are second in out of the box sharpness. I do prefer the montecs however, just because they have the highest carbon of the three, which makes them easy to resharpen.
