In reply to itselliott_:
Biggest and most important difference is the renegade has a floating waist loop and the mithril doesn't.
This means unless your bang in the middle of the sizing you will wind up with the loops offset in one or tother direction which I personally find quite irritating.
Both great harnesses but I'd go for the renegade or another viper if your keen on dmm or maybe a petzl Aquila if your after something comfortable with lots of loops.
