1850 Dark Eldar/Grotequeire formation/ALSO DS/reserve army

I will likely be getting in a game or two this weekend to try the lists out.   Not sure if I should try the grotesqueire list or the reserve army?  I am really on the fence here.  Maybe try both?

I will prob do a battle report of these as well to share what I learned. I will of course need more play testing, but this will count for a good bit I hope.
