Out of those options, I've had the full size and mini Barrage, as well as the Blur. All great knifes, although I ditched the mini barrage because I found it difficult to get a solid enough grip on it for how strong the assist mechanism was. It just didn't feel firmly planted in my hand as that blade swung open.
Both the blur and barrage open with plenty of force, have solid lockup, and lotsa blade real estate with the blur having a little bit of an edge in the slimness department. The pocket clip on the blur kinda sucks compared to the barrage though.
Having them both in my man purse, the ZT0350 is still what is in my pocket at all times though =)
The griptilian with tanto blade (partially serrated) was my first foray into knife land and still remains one of my favorite all time knives save for the fact that I lost it camping. Lack of serrations and tanto style have won me over though just for how much easier it is to maintain the edge on a straight blade.
If you do go for the Blur though, be sure to check out this thread for better pricing. I think the s30v model is obtainable from amazon in the neighborhood of $43 plus any shipping (or in some places tax.)
