I think #2 would sell the most, but would change the angle of the butt so it's better for palm support in forward grip and thumb capping in reverse grip. The spine end being longer is more suited to larger knives you would want to get a 2 or 3 finger grip with lanyard attached for a little chopping - don't like it for folders and small fixed blades.
If you do go with #2, it would be nice as the "A.G. Russell Boot Bowie"
