The twin or base height coilover thing is a gimmick, all it does is lose your valuable stroke.
You will notice after 3 laps that the car gets softer as the dampers go off. Twin tube is bad and D2 is worse.
You also mention that you can put bilstein inserts in them, well technically yes you could, but youd be going so far backwards it wouldnt be funny.
The shortest bilstein inserts use only 30mm pistons (D2 use 20 or 25)
You need uber short inserts becasue the D2s are designed to have less stroke as thats what the boy racers love, they like lifting wheels in carparks etc.
The next size insert in bilstein is a 36mm, and its still not great for you intended use. this is what they use in ALL commodore fronts and most silvias etc, but not skylines
To put in perspective, the off the shelf bilsteins for supras and soarers use 46mm pistons. These are the run of the mill ones too.
HSD is not a great damper but they do have some good points, 2 being mono tube, and inverted in nissan fronts, as well as 45+ mm pistons.
They might be behind in dampening but they are half way there, but considering you only save $500 going to a HSD or D2, I just dont understand why people do this.

I can't do the doors...no cage. I'd be wanting to keep some side intrusion protection.
