Grot mayhem list (1000 Points)

Hey everyone , I was lucky enough to get a ticket to the Warhammer world double weekend in October and have been having trouble deciding between taking my current Kabal list (which won me third place in my first ever tourney!) or branching out into some Prophets of the flesh covens.
Before I tell you my ideas , there are some restrictions on what I can take for the event which are; No more than 2 of the same unit and no more than 2 detachments (wont really matter at 1000P) .


I have been thinking about something roughly like this:


Spearhead - Prophets of the flesh


Urien


Haemonculus - Electro whip and Vexator mask


Grotesque x8

Grotesque x 8

Talos - Haywire blaster


Talos - Haywire blaster


Cronos
