Low points, so simple and mulitple cheap units (I might have List OCD, thus most units are fielded in multiples)
Thought being use the Talos to hold the vehicle mounted heavy stuff up while they advance using as much cover as possible (or maybe have one or more come through the WWP depending on opposing army makeup). Man-portable Heavy stuff the Venoms concentrate on.
Grots w/ Haem and Wracks x2 held for the WWP (possibly a Talos or two as well).
6 Scoring Units, 48 @ 36" Poison Shots, 11 LQ Templates, lots of poison CC attacks, and FNP.
I might consider dropping NS on one or two of the Venoms to upgrade one or both of the Haem's to PWs since they will have FC (2 Pain Tokens), add a Shattershard (mmm goodness) and/or upgrade any Talos coming through WWP to TWHL.
I think it would be fun, look cool and its definately Coven.
