Of those eight, the two I *HAVE* chosen, and bought, are the BM 941 and the Mini-Rukus. They both fit my hand, have axis locks, and are tip up, all of which are big deciders for me. The 941 is a great slacks knife, lightweight but up to the job. The 615 is a tougher than nails tank, which still isn't huge.
I don't tend to buy liner locks much anymore, which cuts out a lot of your list.
