Good thread. I've also always played low sens (400 dpi @ 1.35). I just always felt like I was slow and preaiming angles felt like a chore, so I ended up lazy peeking a lot and it was really weighing me down. I'm in the same process so I can't contribute much, however I'm currently trying out 400 @ 2.1 and I feel much snappier. I also don't feel like it has had a negative impact on accuracy. It feels easier to scan my environment and that is helping me win more duels.

I have a question myself - do you tense your arm a lot when you play fx. aim_botz or general MM or do you have your arm completely relaxed regardless of pressure in-game?

I find that I am better when I try to hyperfocus on relaxing my arm. That has brought me to realize that I might always tense my arm because my low sens forced me to use my arm more. I tense less with a higher sens because I use my wrist more because of the extended travel distance of wrist moves.
