Hey, BJE, how is the Vex treating you? Any edge retention differences jumping out at you? How about the blade grind's cutting efficiency vs. the G-10 Cara Cara?
My new G-10 Cara Cara is better than my first (I gave it away), it has no blade play at all, impervious to spine whacks, and holding it's very sharp factory edge well. The only minuses are the finish on the sides of the lockbar are rough, and the finish on the tang where it locks up looks like a bastard file (really, it does). After a couple of drops of tuf glide though it is smooth and functions flawlessly. I will be thinning the angle out significantly as soon as I get the time (fitting that into a 60+ hour work week and spending time with the wife and kid can be tough) to see how it performs. I would be interested in trying the Vex, maybe a passaround would be able to get worked out.
