I'm not sure how you guys are using 8 sens etc. Currently using 32 sens with 12k DPI and it's just enough to turn around in 1 comfortable motion. Tracking isn't an issue at all with this sens either. Using the Logitech g303 and cloth mouse pad.
I wasn't sure about this at first, but after a few games, I definitely think this is better than the current ST. Took some getting use too, but already I'm doing a lot better. Though I've missed a few kills I would've gotten before, I'm going to attribute it to being the first day using this new config and I'm just not attuned with it yet.

100 Aim Assist
25 Aim Window (Might lower this to 20 - 24)
0 Aim smoothing
Been using it with Soldier and trace primarly, and it feels pretty good. Did some games with widowmaker, flicks feel pretty good, I will have to try a low sens and tracking, but I prefer flicking with widow. But overall the new config feels good with everyone.
Thanks a ton for this post!
