I've started a 1k list just now: it's not all troggs though, and not really optimized for anything; just models I liked.
Troggboss
Arachnarok with shaman
Rockgutsx3
Rockgutsx3
Sloggoth ally
You will want a troggboss and rockguts, that's for sure. You will also want fellwaters at some point, and the sloggoth.
Sloggoth +1 to hit with troggboss CA has troggs hitting on 2s rerolling 1s.
I'm personally making 6 rockguts per kit with greenstuff legs and guts.
So if you want to not get doubles from the secret Santa I'd go for either rockguts or fellwaters, since you wont want two dankholds or sloggoths yet.
