You're the guy that I talked to about the SLR20, haha. I didn't play Y1 Trials, so I can't talk there. But Hidden Hand is a noticeable difference on the gun, and iirc, 1000 Yard Stare can get up to about 85 or so AA, which is higher than a lot of Y1s, if I was linked to any proper AA pages. I think it is rather stupid that a skill would allow you to keep a target "locked onto" for an extended time, which is net boost overall to helping you land headshots. It's also one of the only of its kind- High Impact, High Aim Assist. AA doesn't determine your skill, curve bullets, or any shit like that, but it certainly helps you land head shots.
