Here is my Perseus MPCV in 3 versions.
All versions have 4000+ electric power, yet no power source, so if you are going for long duration mission add one to service module.
Those are safest manned crafts I have made so far.
Light version:
weight: 6.7t
parts: 21
d/v: 600m/s
engines: 80kN
power landing: starts with full thrust at 1300m
Medium version:
weight: 8.2t
parts: 25
d/v: 1000m/s
engines: 120kN
power landing: full thrust at: 1100m
Heavy version:
weight: 9.7t
parts: 27
d/v: 1350m/s
engines: 120kN
power landing: full thrust at: 1500m
If you are new to capsule power landing I suggest medium version for practice. It simply gives you more time, than light version, and have largest TWR.
For few hours LKO mission on different orbits I suggest heavy version, since it shouldn't need any service module with additional d/v or power source.
