You look to have 5 synapse and 6 things that need it...If you lost 1 Brood of warriors thats 20 Hormies, or 25 Termies it might be a good choice. At low point games Monsters dominate, so your troops are safer. Untill some wise guy decides to try rubbing your troops out

So I'd suggest trying it both ways.
If you have luck with a big Term swarm, you can build a Tervigon for larger point games...Big Monster, Synapse, spews out extra troops...a good time for all

Just increase the 25 Term's to 30....
At higher point totals a Hive Tyrant becomes much more of a "must have" I ran Prime(s) in 5th, but with the boost in point cost, my 1500 list uses a Tyrant (that I used to add in at higher point games) Not much more expensive, and it's a Big Ugly Monster (
tm) I add the prime in for larger games...but will likely replace it with a second Tyrant, once I get one as a birthday or x-mass gift...
