The two main choices I need help with is this list which is slightly varied, a Zoanthrope, Biovore [the spore mines], Trygon and two Tervigons [one as troop, the other a HQ with Regeneration (which worked out well last game)]...
...or slightly less versatile three Tervigons, two of which are troops.
Option 2. still has the same amount of Synapse and Psykers but I get the extra durability of the second troop Tervigon [not to mention the 2 broods of 30 Termagants] spawning will be limited in places, I just don't have enough gaunts but I'm hoping that enough will die for me to respawn them.
Ultimately Option 1. is probably more fun for people to play against, Option 2. fits my 'fluff' in that they are defending the Hive Nest - the Bastion, Skyshield etc.but it's 3 Tervigons! Will I be 'that guy' if I run it? I may survive to the end of the game - when you go Stronghold Assault it's endurance not attack you're planning for but spending most of the game hiding... but, it's the first time I've been able to run three.
I may get a chance to try this out tomorrow night on Ben but any opinions on these two options would be greatly appreciated.
