I've been shooting Zwickeys my entire bowhunting career (all of 12 years now) and they have never once let me down. However, now that I'm shooting a faster and smaller bow (Vipertec) I'm concerned about their flight characteristics at longer ranges. Not due to the broadhead design itself, but my ability to glue the head onto the adapter perfectly straight. Not to mention the weight of the 2 blade is somewhere in the neighborhood of 140 grains after glue and insert. So needless to say, I've been debating what to switch to this year as well. The Montecs look nice, but I'm still not too keen on what I've heard about their resharpenability. Plus I like a 2 blade design over a 3 blade. I've been looking hard at all the heads on the market and I'm starting to lean towards the Magnus heads. They seem to be one of the best solidly built heads out there, and judging from the looks of them they will be able to be sharpened in the same manner as my Zwickeys. I bought a sharpener a few years back that is shaped like a "V" with a file on either side that you just run the head across. I have a set that has actual files, a set with stones, and finally one with leather stropes. I was able to get my Zwickeys sharp enough to shave the hair on my arm, which was plenty good for me.

By the way - isn't the Nuge Blade made by Magnus? I've been looking at those as well.
