It's great fun ain't it.
Vg if I understand how they work, as I've never flown one with it, clean up the airflow and keep it attached for longer and invite you to be able to land even slower ??
Modern aerodynamics have the VLJs and most of the small jets and some of the bigguns with Vref lower than your C310R.
The C310 R like the Baron, started life as smaller lighter ships with less HP and like topsy just grew.
Walk around your C310 and have a look at all of the straps around the rear fuselage/wing and double skins here and there tp pick up the extra weight.
That's why Cessna gave the C310R away in 1981 and concentrated on the Crusader.
You can do assymetrics in that with your feet on the floor, C182 type landing and TO speeds.
drop gear and flap at CRZ speeds wthout any trim change, pull 60degree accelerated stalls one or both engines and it will simply fall out straight and level. etc etc .
Basically pilot proof and I would have no problems giving the keys to a proficient single pilot.
Have fun
