Centurian: The 722 does not have an overly-long handle. If anything, I feel it's a touch short! Emerson's knives, on average, have the worst blade-to-handle ratio in the industry; I am confident the 722's handle is shorter than the CQC7's. It is also shorter than the Stryker's.
Lizard king gave very good advice. Handle them all, see if one handle or other just doesn't work for you.
I agree with Dexter on the slightly-awkward aesthetics of the 722, but for a carry-and-use knife, aesthetics don't bother me that much. If it performs well, it ends up looking purdy to me

I am bothered more about aesthetics when the knife is not intended to be used as much.
I also agree with medusa o. on the Sog Vision! Cliff had a Zytel-handled Vision that he wasn't too impressed with, but my g-10 handled version is very sound (although it costs much more than zytel, obviously). There have been a couple reports of Arc Locks developing some play in use, but I am definitely not sure if that is a trend or just a couple random reports (locks developing play is something that gets reported on most types of locks, eventually), and I believe Ron at SOG would be interested in making it right, if it happened. I beat the hell out of the Arc Lock in that knife, I slammed it on its spine, I put the blade in a vice and torqued the handle, etc., and the lock was rock solid (except for eventually developing some play, which again, SOG believes is the exception).
