I vote shot placement. I think any sharp BH will work as long as you hit both lungs, so it mostly needs to fly well with your setup. Since switching to recurve I've tried Iron Will, Magnus, VPA, RMS Cutthroats, and several more. I liked some better than others mostly for the materials, and second for design. I can sharpen some better than others because of the steel, but like the design of a few that I cannot get as sharp (Ive made knives for about 30 years fwiw). Last year I started making my own with 8670 steel and using a titanium body..it's a combination of my favorite design features, but with a steel I can control the heat treatment of to be both sharp and tough. The titanium body is prob overkill but the weight comes out at 150g and they look cool. Deer die the same with them as any others I've used, but it's very difficult to make the all the same with my manual lathe and mill...I wouldn't use them with my compound unless I really upped my consistency.
