Mine is the recent black blade, black clip version. I find the handle to be one of the most comfortable I've ever handled.
It is very "handle-heavy", but I have no problem with that.
Some have felt that there is not enough blade length for the handle size. I feel that 3.6 in. is plenty of blade.
As to the lock up, my sample has about the strongest lock I've ever seen, short of a Sebenza.
I am not an advocate of "spine whacking", but I have done a bit of moderate tapping on the spine and have not been able to get it to fail.
Slow twisting motions have also not caused any lock failure.
The VG 10 steel is great and the grind lines and edge geometry are in the custom class.
Overall, I'm very pleased with this knife. I've been carrying it almost daily for about a month, so that says something to me right there.
As I subject it to more rigorous use, I'll report back.
Good luck with your SERE 2000.
