I actually VDR'd one of these up, and made it a super Venom, actually exactly the same as your model with AV 11 all around and a Holo-Field. I think it came to 120 pts, but it's been a long time since I made it, so my memory might be a little shaky. I think I had it able to carry 1 IC too, which would be wonderful for my newly-developed super DJ, Endbringer. Though, for 220 pts, it'd be a tough thing to lose, especially for the Harlies. But, with TL Starcannons, plus carrying Endbringer, with his BS5 BL, he'd make quite a dent in anything armoured that's thrown at me. Now that I make it up, it comes to 164 pts, with BS4 and no Holo-field upgrade (the standard points value). I think I could spare 280 pts. in my army to put this beast and Endbringer in.
I like the name, too. The Poison Arc sounds quite evil. Anyone else made one of these?
