D.I.D. & RK are good chains depending on the model and it's tensile strength.

I run a RK 520 XOSO  (8,500 Lbs tensile strength).

Fuss ran a RMATV chain for a the last couple of years and it worked good, plus the rivets are preened over so they don't catch anything or do a lot of damage if they hit something like the frame.
