secureteam10 - although Tyler has been putting videos up a lot less since his dad passed away. I actually don't believe a lot of the alien stuff, I just like the way his content exposes stuff and makes you think.
Law & Crime - gotta love those body cam chases.
TheWhyFiles - I love AJ and really came to love Heckle fish!
EatSleepYangon - although I haven't watched it in a good minute, plus they're recruiting younger and younger and thinner and thinner girls now which has driven me away. Alex is my favorite and is like the only woman on there.
UniverseInsideYou - she posts a lot of great stuff but less than she used to.
