Other options include Retrofire Jets, Chain Snares, Grisly Trophies, Envemoned Blades, and Night Shields. You start the game with a flickerfield which gives you a 5+ invul save.
One of the nicest things about Raiders and Venoms is that they are opposites. One carries a dark lance or disintegrator and carries 10, while the other will have 2 splinter cannons and carry 5. Using the two of them, together really gives you great flexibility on the table top. One able to take out heavy armor, the other massed infantry.
One thing I love so far about poisoned shooting weapons of the Dark Eldar is the need to not care if those marines are in cover or not. It's easy to put down a hail of fire at a great distance with a good ballistic skill. The Venom truly excels at this. Moving 12"s with such a great range, really means you can almost always see and reach a target that you want to shoot at.
The tricky thing is to figure out what goes into the venom. Some units just don't seem to fit with a venom. You can only take 5 infantry in order to get the venom and this is the limiting factor. You need to have an efficient 5 man unit to take with the vehicle.
I like Kabalite Warriors and Trueborn the most. 5 kabalite warriors with a blaster and sybarite with a blast pistol are on the top of the list for me. Trueborn with a venom work, but in general I don't like the idea of suiciding my trueborn, so I prefer them in larger numbers.
When looking at maximizing the unit that rides the venom, both wyches and wracks require 5 models to get their special weapons. This means no independent character. I see this as a drawback, as it limits my flexibility on the tabletop at deployment. While this isn't always an issue, it makes me look at other unit types to take the venom, and makes me want to give wracks and wyches both raiders.
Overall I really like the Venom. In a force were you have several raiders, taking a couple venoms really are going to fill in your list. Currently I am fielding 4 raiders and 2 venoms in several of my lists, and I really like the flexibility of it. I keep them cheap, and don't add anything but the extra splinter cannon and they work out real well. You will see a lot of players taking venoms, whether its because they are playing multiple small unit (MSU) lists, or because they really like how cheap it is to get those 12 poisoned shots. Not to mention that it looks like we will getting a model for them sometime next year around summer time.
