DAP is flying sex! There have been 0 changes in the 60's main or tail rotor designs until the UH60M model where they did away with the BIM indicator and made a different blade design to keep the tip caps a little more away from the speed of sound. Resulting in a quieter bird. Unfortunately only 1st CAB and few NG unit have the "mike" model. SOAR uses the mh60k variant which still uses the uh60L rotor heads. They just get the good stuff like autopilot, flir, weapons controls, midair refuel, external hoist, and dillons.
