Jamnperry, there is a trough around the arm bearing for the damping fluid. The full signature upgrade replaces the tonearm, bearing and support assembly as well as the junction box. The wiring is now by Nordost and the anti-skating mechanism is a mechanical one and no longer accomplished via a twist of the tonearm cable.
As far as the outer ring clamp, center weight combination and new motor flywheel, dialing the speed at a stable 33 rpm is a breeze via the KAB SpeedStrobe and the SDS. I have no idea how one can achieve speed stability without the SDS and KAB Speedstrobe because of the additional flywheel and platter mass.
I went from the Scoutmaster to the SuperScoutmaster Plus (ie nordost signature arm) with a new Shelter 901 cart. Still breaking it all in.
