There are a lot of choices out there for broadheads and I don't believe anyone can tell you which head is perfect for you.

Some people really like mechanicals because they are very easy to use and in most cases offer a larger cutting diameter. Really, you just unscrew your field tip, screw a mechanical on and get in a stand. Mechanicals help hide some tuning flaws with your setup and shoot just like a field tip.

I personally don't care for them for a couple of reasons. 1) They rob KE from your setup. 2) I have concerns about the durability of most on the market. 3) They are mechanical, so in my mind, that is just another possible point of failure.

Fix blades broadhead are what I like the most and more specific, cut on contact bh's. However, they have some problems as well. First, if your bow is not tuned correct, your bh will not have the same point of impact as your field tip (in most cases). This means you either have to tune your bow (best option) or adjust your sights for their POI. However, I believe that they are worth the extra work. They cannot fail, the blades will always be there to cut and you get better penatration.

You mentioned Muzzy and that would be a hard head to beat. They have been around forever and have taken a ton deer.
