I use the abomination pack in every scenario and for the most part I feel like it doesn't make it too much easier. If you put in the George A Romero cards, it is likely you will run out of walkers anyways.I usually just house rule the second abomination and ask the other players what they want to do. I explain that the rules say to just put out a fatty, but that we can put out a second abomination since I have one. Most of the time they say to put out a fatty. :-)
If you do only want to use your extra models on a few scenarios, I would suggest any that have 4 or more spawn points since those are suppose to be the hardest and you will likely run out of walkers early.
