Similar thing can happen with Daisy chains when shortening them. If you don't twist them you can end up with the biner only clipped around the bar tacks and not actually clipped to the sling. If you then fall on it (even a short distance) you can rip out the bar tacks and then fall further...

Every system has its pros and cons. in this case a well placed twist round the biner) will eliminate the above risk.

Regarding the WC Syncro harness, this is being replaced bu the Wild Country Summit, a truly awesome harness, that I was luck enough to test 2 months ago.
The 6 gear loops are amazing. I tested a pre-production sample, Will be available Feb 2012
