100 $ stack in 1 $ / 2 $ blinds room sounds too high for me. That means that there are at least 1 aggressive type of player in the room that is not afraid to risk his/her money. That can be good for you but also it can be bad for you. You can win money faster than it is usual for 1 $ / 2 $ room, but also you can lose money fast.
100 $ + stack is maybe an average pot in 5 $ / 10 $ room.
In 1 $ / 2 $ room I prefer an average pot between 15 - 35 $
