I think it is a bold move to request help in order to cheat in any competitive game; even if you won't get caught steam account dipperftw will be tainted by this thread. I hope you keep it clean and get a normal pro gamer mouse, Deathadder is a great choice. Nothing replaces putting in many hours of training per day against bots and knowing your maps and squad tactics.
Oh and mice that employ anti recoil scripts can be detected in their non-human like recoil control and burst accuracy statistics and can potentially be used to distinguish the cheaters from the non real players.
