Mule kick would be ideal since when doing the ee u almost always need the maps WW for a step so that limits u to just 1 other gun and if it's not a very good WW like the beamsmasher since it is very underwhelming compared to the ray gun or jet gun even, then u are in an even worse spot so mule kick would be preferred. Double Tap would also be acceptable but no death perception, tombstone or even vulture aid please
