I think I will leave it without decals. Still need to change some components though (Avid Arch Supreme but I still need some SL-M952 in VGC for that ... shouldn't have sold mine couple of months ago ). And maybe a syncros Revolution .. but that one need a treatment as well yet.
Personally, I would remove those green tires, though. Then, the blue 97 decals will fit, too. If you want something fancy, why not choose Tioga Butterscotch? I had them on my Xizang once (but it was too much).
You got your Xizang brushed, right? Without decals one could think you "only" have a Lightning.
Not too sure about the Avid Arch Supremes. Of course, they look cool and are the most exclusive V-Brakes out there - but they are quite heavy and their polished look does not fit the titanium colour too well.
Also no "need" to switch to Syncros Revos. I love M950 cranks (in nice condition), especially on Ti frames.
