Where to expand?

[ralphinator]

I have a basic 1500 list that I run and am comfortable with. However, I'm unsure as to how to add to it at point levels between 1500-2000 where an additional force org slot becomes available. I'm maxed out on HQ, Troop, and Elite slots, which are in my opinion the strongest in the codex.

HQ

Flying Hive Tyrant, Tl Devourer, Lash whip & Bonesword 245

Elite

The list at barebones is 1450, and I add an extra psychic power on each tervigon to bring it to 1495. At higher point levels I usually use a squad of ymgarls, and was thinking of instead investing in 3 more hive guard. But either way, I'm left with extra points unused, which I end up spending on upgrades (AG and powers for tervigon, regen for tervigon and tyrant) because I'm not sure where else to put my points. What FA and Heavy choices have you guys had good experiences with? Trygons and harpies have dissapointed me so far.

I'd say you really want to add both psychic powers to each Tervigon if you are looking at playing with lots of psychic goodness.

Why not expand the gant broods? Giving one devs and a spore at 15 models could also give your Tyrants more support for when they push forward and give you a scoring unit in the enemies backfield.
