I'd have to throw in another vote for the Wave, although in all fairness I've never used either of the Charge models.

Pluses of the Wave:

One-handed blade opening without having to open the whole tool - VERY useful!!. The Charges use a better grade of steel for the blades, but hey, I'll take what I can get (especially since I value my money).

Locking primary blades - very important!

Crosscut file, diamond file, a decent saw (great for relatively small branches and yes, PVC), good scissors - all very useful tools.

The pliers on my Wave (the old one) are much beefier than on the original Leatherman PST or any of the other "original" series, and the new Wave is better yet.

Frankly, now that I own a Wave, I'd never want to go back to using *any* multitool that does not have one-handed opening of at least the primary blades, and I'd never use a non-locking blade for anything but the most trivial task.

I also carry a Micra - I find the scissors a little more "balanced" in the hand, and it's more PHRASECENSOREDPOSTERSHOULDKNOWBETTER.-friendly. It looks more like a novelty than a "weapon" in their eyes, so when I'm in mixed company I'll go to that first.

I carry a Flair sometimes, mainly for the corkscrew.
