I don't have that one either, I do have a Flash 2 and a Spec Elite 2. The Flash is assisted and the Spec Elite is not, to be honest I can open them both in about the same time. I looked for quite some time at the Twitch and Twitch XL, basically a larger version of the Blink. The one thing that gave me pause was the smoothness of the grip. While it's not polished, I worried that if my hand was wet or sweaty it could be hard to hold on to. The clip would probably help, but for the money I decided to go with something else. This is by no means an expert opinion, just my FYI, I got my Flash 2 off Ebay for about $36, it's bulkier than the Blink and has a safety but is over an inch longer. Not that size is everything
I've got the blink. It was a little too bulky to put on my keys, but has a lot of great features. Problem I found was that it's such a small blade; the spring assist and locking systems as well as the with on the handle are a little over kill. I have no doubt this thing could survive a trip to hell and back but it's not practical for me
