he uses crazy mouse accel, not sure what the values are but it was fucking weird to try it at i52.
a low sens is OK to use if you're comfortable with it, the issues start when you need to be able to make quick movements that might take longer with a low sens. You want to be able to do a 360 comfortably, even though you won't do that much in game it's still important as your aiming ability will always be stretched, don't forget you have to look up and down too.
another issue i find is that a few low sens soldiers that used to play (haunter?) you could always tell when they were going to rocket jump as the movement took longer for them, you could just prefire and that's it, against high sens. soldiers they can just jump instantly without a long animation that their player model shows.
in relation to tek who uses mouse accell, he'd never really struggle on quick movements because of his settings and could still accurately control his aim.
