750 Point Patrol Detachment

So I have a little tourney coming up and Im just starting up the Dark Eldar so looking for advice on a good 750 Point list that fits into a patrol detachment? No names characters or lords of war allowed. My initial list is:
Archon, Blast Pistol, Agoniser
4x 5 Kabalites with Blaster
5 Scourges, 4 DL
2 Raiders with Disintegrators
1 Venom.
748 Points.

Biggest issue I see is that you can't take 4 Troop options in a Patrol Detachment.
Working in a Ravager could also be very sexy, it's an excellent unit and pretty affordable. I'd dare say it's superior to the Scourges in all ways that matter at 750.
