I've had this one for about 3 years or so, and really like it. I like the mild re-curve, light weight for the blade size and the way it snaps open quite hard.
I would prefer tip up carry on it but I have no real problem with tip down. The edge of the clip provides over travel stop for the lock bar, a simple and effective feature.
There is no steel insert on the lock bar, and from my experience with it, it just doesn't need one.
It's the only assisted folder I have that I'm wary of it opening in my pocket. It never has so maybe my concern is unwarranted, but the detent just feels less convincing than, say, the 581 or 586. The 790 I can quite easily get to open with a sharp jerk of the hand, which a Barrage just won't do.
The blade lock on a Barrage I never use, it just doesn't seem to need it.
There's no blade lock on the 790 but if there was I would probably use it.
The handle is no ergonomic wonder. Partly 'cos the lock bar at the interface end sits lower than the opposite side of the handle, as you can see in the pic. So it's not the most comfortable for extended use.
But on the whole, I really do like this folder. It doesn't get carried very often, but it does get it's outings, sometimes in a zipped vest pocket as a secondary carry as it's nice and light.
As a general EDC folder with a strong AO, I like it and have no intention of parting with it.
