What mask do you guys find yourselves rolling with?
I find myself exclusively using Jake The Snake, which makes any thrown object lethal. This is especially useful because thrown objects don't stop after colliding with someone, which means if you can gets a row of dudes lined up, a single throw can wipe all of them out in one fell swoop. Since thrown objects also ricochet of walls, you can do some crazy shit that way too. Kills from thrown objects are also silent, and you can throw them from fucking deep.
The only significant downside is that the thrown items only hurt regular enemies...they don't make contact with dogs or the heavier guys. :(
