I have one, but I find it a bit too big and heavy. Also, it has more layers on one side of the pliers than the others, which offends me.

I also have the S2, which is equally asymmetric but somehow doesn't bother me as much. It's significantly smaller and lighter than the CS4, but still has knife, pliers and scissors and the range of screwdrivers. It covers the basics, and for me every extra tool the larger ones adds is worth a bit less.

That said, I'm currently carrying the CS4 which is intermediate (and the most symmetric). That's partly because I made a discrete paracord belt-loop so I think I can afford the extra weight. Also because the S2 hides the scissors behind the bottle/can opener, which makes it slower to deploy.
