I'll add my 2c:
I own a 2016 DSR with PT. I've spun up the rear wheel on my 2013 DS, but not the DSR, partly from experience and partly because I use a crampbuster to help me stay aware of the throttle position and not accidentally torque it too much. The PT is indeed pretty hefty and does make the bike harder to lift if you drop it, but handling is fine. I always ride in Custom mode (100% torque, 0-20% coasting regen, 100% brake regen).
My bike also has a Hollywood Electrics fairing, a Corbin trunk for the Concours 14, 5 DigiNow units (3 in the pan and 2 on the side), and a reverse mode switch. My range varies between 100 (cold day into a heavy headwind) and 135 miles (warm day with no adverse winds or rain). My range is at least 150 miles at about 45mph.
I've logged about 40,000 miles now on the DSR, with 26,000 miles on the 2013 DS.
