I like list two....
Here is an "alternate" 1000 point list. It takes the Tervigon as a
HQ.....
HQ: Winged Dakka'rant, Thorax: Electro 240 + Old Adversary 255
HQ: Tervigon, Thorax: Electro 205
Troops: Warrior Brood, x3 Cannon 100
Troops: Hormagaunts x 12 60
Troops: Hormagaunts x11 55
Elite: Venothrope
Elite: Veno
Elite: Zoey
This has no Heavies so it is a little weird, but can build "up" easy. It has lots of Troops, and two
MC's as
HQ.
This is more of a "anti-Tau" list
HQ: Winged Dakka'rant, Thorax
Elite: Zoey
Elite: Veno
Troops: Tervigon: Thorax: Electro
Troops: Termagants, x 30
Heavy: Dakkafex
Heavy: Mawloc
This is still got 50 points left.
I would look at a small Brood of Gribblies. Like Hormagaunts x10, or x3 Tunneling Rippers (45)
Mawlocs are a very solid answer to Tau gunline habits. Then you can form up a "Bug Star" with the Dakkafex, Zoey, Veno, and Termagants. Then you just concentrate on killing the Marker lights.
