I don't like not having control over how quickly or slowly the knife opens. I also don't like the crutch it gives people (imagine a rifle scope that automatically creates bullseyes without even trying)...
They actually have created this-- look up the Xactsystem "smart rifle." For a mere $22K, you can hit that 10 ring every time supposedly up to 1,200 yards.
Taking all the art and skill out of it... :grumpy:
Back to the subject at hand though.
Personally, I do not find the compression lock harder or easier to use than the Axis lock.
Both can be deployed and disengaged equally quick, ambidextrously. Some left handed people say they have issues with the compression lock... I don't get it.
Like Cypress, I am also not a fan of assisted folders-- was once super amped on them, but in the end found that (for me) they were not any faster.
In fact, the assist mechanisms created a chances for the knife to jump out of my hand, even while closing (again, maybe that's just me)!
The Barrage is pretty rad. It's got clean lines. I like it.... even steered my uncle towards one, which he loves.
However, for the most part, I love a good choil, so I'd still lean PM2. Then again, M390 is pretty sweet, and it's tough to find a PM2 with it.
Spyder hole vs thumbstud is not a big deal to me, but maybe it would be to you. I like both.
