100%, hip currently feels exactly like I'm playing an FPS on PC. It's amazing how much better it feels compared to your original curve, when I already thought that was as good as it gets. Very precise, very 'zippy' and feels like the mouse movements I make are represented on screen 1:1.
What makes you think the ADS is not quite as good in your opinion? Is it the increased aim-assist whilst aiming down sights or do you think it's just the way the game slows the reticle whilst ADS'ing?
(That's not me complaining about the curve whilst ADS by the way, just referencing your post when you talk about how good hip is!)
