I don't know about a Ti finish on the wave.
There's a nice review of the new lineup at:
My current EDC: Victorinox Cybertool 34. Apparently standard issue for astronauts these days. Proved itself handy on many an occasion, I just wish a more comprehensive set of bits were available. I mostly use the tools, but the knives have been handy too. I also have a Leatherman Juice KF4, which is a nice size for the pocket, and is better suited for more rugged applications.
So for my money, I would go for the XTi due to the crimping function (electronics), cutting hook (which compensates for the lack of scissors), and the second bit holder (with an appropriately chosen torx bit). Plus the extra bit set. OTOH, light small pocket sized tools actually get carried by me, so I might not bother.
I was interested in the spyderench because it has something no other multitool has - an adjustable wrench. Which comes up a lot in mechanical applications. My basic motive is "as many functions in as little space as possible" - which hasn't really been met by any tool yet. Heck, I'm still waiting for all the really obvious electronic gadgets to be incorporated into a cellphone.
