Best way to transport incubi

I always include incubi and drawbar in my army. I play relatively small lists so it's just one unit of incubi and drazhar, 6 models total. I have a raider and a venom.

Venom is 5 capacity and raider is 10.

I obviously can't fit drazhar and incubi in the venom and if I put them in the raider there's 4 wasted space. It seems like a disaster waiting to happen to run the venom and raider side by side. It looks to me like I could just be outmanoeuvred and never actually trap someone in to CC.

What should I do?

Run Incubi as Understrength unit with Drazhar in Venom.

I ran them in a raider in my last few games. Can't beat the additional dark lance although the 4 wasted transport slots are a tad annoying. Ive been considering adding in some of the court units to ride along with them, a couple of slyth and a medusae would help with shooting and combat.

Adding a sslyth and medusae is such a good idea. Is it the medusae that gives you re-rolls as well?

The Archon gives re-rolls to the Medusae.

Ah that's what I was thinking of then. Lelith looks brutal in CC as well. Might put the archon, a sslyth, medusae and Lelith in the raider with 5 incubi and drazhar?

Or does that make the raider too high value a target. It would be a CC killing machine but also very very expensive.

I'd drop Lilith and get another medusa or slyyth. And have a group of birds fly with them, raider goes down, suddenly you have a screen that can only be ignored if they want to target your incubi, since everyone else embarked is a character
