CA list tweaking

[Wax]

I've been brainstorming a single-list CA army for a little while, based on making use of as many CA-unique tricks as I can. I've boiled it down to 3 very similar possibilities and now I would like to get an outside opinion. I'm hoping that people with more CA experience can steer me in the right direction in regards to the very subtle differences between these lists. Without further ado, the lists:


The first incarnation. While all the lists have max 9 orders this list relies on a Imetron to provide one, and only has one Dat for the MSVs to play with. That also means only one use of coma, but I figure one would be enough.

The second list. I have removed the Imetron and added a second Dat. The big issue here is I have removed the single biggest CA exclusive item and thus part of the whole point behind making the list. Also, coma will now be useless.

Final option. I keep all my toys, get two Dats, and don't have to deal with an Imetron, but I only have 8 orders...

I guess my ultimate question is: Is the first list a good option; or by relying on cheap orders will I find myself anemic when it comes to models I can actually use to kill stuff with?
