I came up with this list when walking to Uni today. I haven't checked my maths so I may be a few points off.

Not intended to be competitive, just for fun.

HQ
Mad Dok Grotsnik

Big Mek
KFF

Elites

3 x 15 Kommandos
Each mob has 2 x burnas and Nob w/ PK and BP
One mob has snikrot instead of nob

Troops
20 Shoota Boyz
Nob w/ PK, BP

19 Shoota Boyz
Nob w/ PK, BP

Fast attack
2 x 1 Deff koptas
Buzzsaw

Heavy support
2 x Battlewagon w/ Deff rolla and big shoota

Looted wagon w/ Boomgun and 'ard case

Comes to about 1750

Idea is to stick the Dok with Snikrots unit and have them sneak in as usual but backed up by two more units of Kommandoes. Rest of the stuff makes a fire base and does what they do best. Deffkoptas are used to Kamikaze units to take out Heavy weapon squads and tanks.

C & C welcome

Seems really fun, a list themed around decoys and throat-slitting.
I can see how each unit would be used, so I cannot think of any changes.
(Except: I do prefer rokkitz over buzzsaws. They can do the same thing except do it again and again and again without getting closer than 24"!)

Battlewagons filled with boys strafing the enemy while hooting and hollering. Looted wagon makin messes of enemy formations. deffkoptas buzzing around over head messing enemy armour and heavy weapon squads. Kommandoes pouring into ranks from behind....the enemy won't know what hit 'em!
