"Kinda blatant" + Speed and killaura isn't kinda blatant. May aswell pop on with Novoline or Astofpho if you're gonna hop. I'm not sure how much speed bypasses, but it's pretty safe while you have speed.
Also it depends on your ping.
If you don't care about getting banned, use similar settings that Wauls used. Use 3.5-3.9, 0.15 hitboxes, Aimassit (Personal preference), autoclicker 12-16, toggle on keepsprint, Killaura (Defult settings + Autoblock + 800 switch delay) and 30% Horz. Velocity and visuals.
If you're going closet, just use 3.1-3.4 or smthn, toggle on max aimassit 80% velocity, and 0.2 hitboxes on hoppers.
Semi blatant != Speed nor Killaura, in my opinion
If you'd like to cheat, and have an account last for about a month, use the same shit that Japhour used. (Smthn like 3.8-4.2, 0.2 hitboxes.)
