In my experience Ember regularly reach 65mphFrom my own observations, yes. The downhill section on Wellington Road in Aberdeen which is a 30mph limit is another bad spot, particularly at night.
With that said its not exclusive to certain Citylink sub-contractors. Last month i was in a van on the A90 between Dundee and Perth sitting at 60mph (the speed limit for that type of vehicle) and an Ember coach went flying past in the outside lane so most definitely wasn't sticking to the 60mph limit.
