Zed, you are wasting way too much time switching characters to get only 1 guy on your replay or to keep your death count low.
Its faster than dying in a lot of levels, and its easier for me to be consistent from switch character since I control that exactly. (and I can fly through the menu in about 1/3 of a second now, which is about as fast as the death animation anyways :) ).
Also, I may or may not try to contribute to an IL table on sda eventually, which seems like it will at least require that due to a lot of the bugs/oddities surrounding restarting from death.
I record live, so replays aren't that important to me (although I do save them).
