In reply to lcullum7:
My wife got a WC (not the Vision, but the Elite Ziplock), after trying both (and many others). Just came down to fit in the end (and Vision and Elite fitted same, difference was only in weight/gear-loops/etc.,). What I thought was cool on the WC harness were the number of gear loops, the 10kn haul loop, 10kN accessory clip in point, pocket, etc.,
The WC harnesses seem to go in for these extra features (the Syncro claims 7 gear loops). Depending on your perspective, that's good/bad
