For the DRUM SOUNDS I am pretty happy with the combination of Bogaudio Sine Oscillator, NYSTHI AD and Vult Punch and Freak (or other Amps and Filters with Drive/Saturation/Distortion). For the kick I find it important to have control over the starting phase of the oscillator, to get consistent attack transients. I have downsized my Drum Synths a bit by using the phase modulation input of Bogaudio Sine and the PW input of Bogaudio Pulse to mix in some noise for snares and hihats.
You can see my drumsynth here, in the lower left corner of the screen:
Another very good small option for hihats is to use two Pulse oscillators and have them modulate each others Pulsewidth, while the classic approach would be to use six pulse oscillators to create metallic hihats and cymbals.
