Are Busse knives on the heavy side or light side? Well balanced? Do you lose any control of the point yet still maintain maximum chopping power?
Busses are generally on the heavy side, but the Mojo really isn't. It has a distal taper (the blade thickness starts at 1/4" at the spine then tapers to a thinner thickness near the tip) and the tang has cut-outs made in it to lighten the knife and balance it. It is actually lighter than the Steel Heart 2, even though it has a longer blade and longer overall length. It feels balanced in the hand (I got to handle one at the Blade show) but also feels like a great chopper. Also (as Cliff Stamp mentioned), the distal taper makes the Mojo very versatile. The tip is great for chopping vegetationg because it can easily attain high speed (because of its thinness) and the edge near the middle and base of the blade is awesome for chopping hard woods because of its thickness. Also, the Mojo has a recurve, making it a great slasher and slicer, a plus for a fighter. The tip actually feels surprisingly sharp, I think, and it would make a decently good penetrater.
Forgot to ask, are the blades relatively easy to sharpen in the field? I'm assuming edge retention is of high quality.
Busses have an assymetrical edge; they have a convex grind on one side of the edge and a flat grind on the other side of the edge. This edge was chosen for durability and ease of sharpening in the field. All you need is a ceramic rod for the flat-ground side and a strop of some kind for the convex side. If you really dislike the edge, you can just grind it off and make a conventional edge.
The edge-retention IS of high quality...INFI holds an edge better than almost any steel, and for hard use, ANY steel. It also is quite corrosion resistant, close to ATS-34. Here are some performance videos showing the performance of the Basics series of knives...the Combat Grade will even outperform these videos:

Here is a knife review that Cliff Stamp made of the Battle Mistress (straight-handled version). I think it will illustrate many of the great points a Busse knife has:

I think the Mojo would be a great combat knife. Its weight, balance, fighting ability, and toughness make it a prime choice.
