I've got two c301's, a c304, and an e307x. I actually like the e307x least of all, the bits stored in the handle make for a horrible grip. They dig into your hand. The c301/c304 on the other hand are both quite comfortable to use. All in all they're pretty nice knives.
I agree with your comments about the e307x. I have one and after 5 mins I wish I didn't order it. Bits in the handle make the unit too wide to pocket carry it let alone a confortable grip. If you use the bits often, they start to slide out and don't stay in the handle (use a piece of paper to keep them in there). The only 'cool' think on the knife was the caribeaner... opened beer bottles with ease!
Its now in my wife's kit in her office. That seems where all my it-looks-like-it'll-do-the-job-but-after-you-get-it-its-worthless items.
