@cgill54 no experience with any of heads you mentioned but I have harvested multiple mule deer with the kudu contour + which is a 2 blade with bleeders & they have performed well.
These are my recommendation as well. I ended up on the Kudu's after considering other heads, but the price was right and they have not let me down. Blood trails will never equal that of a mechanical, but anything I've shot with them have run less then 75 yards and tracking jobs have been obviously short. Sharpening is a little more difficult then a standard straight edge, however with the Stay Sharp Guide it's easy after doing a couple of heads.
