I have been killing deer with archery gear since 1962. I am, and shall remain, convinced that simpler is better whe it comes to archery hunting. I much prefer a recurve .... but those days are ong gone for me now.
For a broadhead I prefer a cut on contact design over any of the mechanical designs. My favorites when I used a recurve or when I used a compound included the Steelforce Premium and Magnus Snuffer. Heck I still have a double handfuls of 150 gr. "Land Sharks".
Because of a shoulder injury several years back that did not respond well to surgery and rehab, I had to switch to a cross bow. I decided to try several boraheads and ended up selecting the G5 Montec 125 fixed blade. The G5's fly super at high velocities and penetrate extremely well. And are as simple as they come. All you have to learn is how to touch up the blades should they dull ... and that is simple.
If you decide to go to a style with replaceable blades, for decades I used the NAP Thunderhead. Never a single issue ... killing white tail deer and feral hogs. Many, many of my frineds have used the Muzzy 3 blades and love them.
As far as expandables, you'll learn that some folks swear by them .. and some folks swear at them. My view is that while they can perform great (and I have seen the end results to that effect) , the fact is full and timely opening of the blades is critical to a quick kill. In my opinion, this introduces just one more something to go wrong. I have seen this sort of failure far too many times to suit me ... so many that I will not use this style of broadhead.
