dunno how a bigger pad makes ur aim sloppier since you got way more ground to cover before running out and you can literally reduce sens to like 90/360 and be accurate af albeit slower to turn.
It depends on pad quality tho, cheap ones are mostly useless. Then theres pad speed, more control based or faster. Many fps gamers nowdays go with glass pads, once u learn to control those flicks are much more accurate with alot less "travel" time for microadjustments (they are smoother to make). But for glass you really need a sleeve because after 5 mins your sticking to the surface in most cases.
