I've found my 75DD far more hassle than a normal pair of fit and forget 75s.
When I first fitted my 75DD with a torque wrench as per the setting they were coming loss every 20 miles. only when I just got an allen key out tighten them up as far as I could have they stayed tight but I'm still paranoid and feel the need to check a couple of time a ride. Also the standard bearing don't have a great rep, I've got 1200 miles on mine without issue so fair.
