I have Superior 2 working perfectly for my own needs – I tweak both S2 and my TD-12 to get the performance I want…
 
One thing I forgot to ask is have you downloaded and installed Superior 2.01? – the hihat performance is much improved.
 
I know John Rammelt uses a Hart kit and I seem to recall it took him a while to get everything tweaked, but once done it outperformed his Roland kit….so I’d keep trying – there’s no reason that S2 should be a limting factor in getting the edrum performance you desire.
