Feathering the clutch is good - you'll get the rhythm. At this point, I find it fine around town, but it is a big twin, so it won't be smooth under about 3k rpm. I'm working the clutch, the throttle, and sometimes the rear brake. Not even thinking about it - took a few months.
In town, I also tend to short shift - quick shifts up to 3rd gear when speeds allow - this helps with engine braking and smoothness.
For me, the rear brake is good for slow speed maneuvering - just a touch will stabilize the machine. I think it's because the revs are up for a given speed, so the gyroscopic forces are higher.
