First thing first that you wanna work on is finding a sensitivity that's right FOR YOU,but you wanna make sure your sens. is low,but with high dpi you'll eliminate any skipping with pixels,and in relation to that lower your sense proportionately. Low sens.=best sens cause it's most steady
ANYWAYS. At first you won't so to speak understand how the methods of aiming are beneficial,or why they matter (not too much at least) ,but in time when it clicks,and with development of your depth perception/spatial awareness you'll come to see aiming as...a motion
,and that's where the fun begins!
(it feels good to flick people up m8,ya dig? )
