500 point escalation vs Blood Angels

[amrogers3]

I have a 500 point escalation game this weekend and looking for some feedback for a list I generated. I have never played Nids before and I'm looking forward to the opportunity to play them. Here is what I have come up with so far:

1 Tyranid Prime, 95 pts (Lash Whip & Bonesword)

2 Hive Guard Brood, 100 pts

1 Tervigon, 210 pts (Cluster Salvo, Adrenal Glands; Toxin Sacs; POWERS: Dominion, Catalyst, Onslaught)

10 Termagant Brood, 50 pts

Total points: 455

If I drop one of the psychic powers, I can pick up a Zoa for extra psychic powers and ability to deal with vehicles.

Suggestions?

Pretty close to what I run. Give the prime regen and toxin if you have the points to spare. Attach the prime to the tervigon and watch your opponent reel as your tervigon hits them all even at I1. Hive Guard are amazing against Rhinos and Rhino variants. Than just fill up with terms until you hit 500.

Dont give the prime regen there are NO models that it is worth it on.

I am playing a similar tournament
my list is
HQ tervigon with crushing claws AG and TS

elites 2 Zoanathropes
troops 17 termagaunts and 18 termagaunts

I havent lost a game yet (i didnt want to run a flyrant)

Regen can be worth it if you pair the tervigon and prime and use look out shenanigans seeing as how both of them are characters...
