The other option is to go mechanized non-armored company Tank Company (3 Russ's, 3 hell hounds, 2-3 grenadier squads). On average you will have 10-11 vehicles plus 25-35 elite infantry.
I am doing a mechanized infantry list and an armored company. I can field an armored company now but it has a large percentage of infantry in it. But I am trying to assign lanes for each piece of the pie. I have 3 russ's, 1 exterminator, 1 demolisher, 1 griffon, 1 bassilisk, and 7 chimera's for transport or recon sections. Now the biggest issue I have is keeping track of scoring vs non-scoring units (transports).
I will say that so far in my 2 games with mech/tanks none of my tanks have survived a battle but my chimeras and troops have had a few warm bodies left over. Even I am still a returning novice player but it is pretty spectacular seeing all those vehicles on the table but it gets hard managing movement and firelanes. That is one of the hardest parts of ACs is that you have all that mobile terrain screwing up your shots.
That and if some one tools a list they can eat through you pretty quickly.
