Bomba Embrague AJP Mineral (Bomba Pequeña) 463029MO0

Hi, french customer here, which pump is the best for TRS 300 gold, for replacing standard Braktec, AJP small or the one with the big reservoir ? which one gives the fastest clutch + lighter pull ? (I see many bikes with the small one / Gelabert, Dufrese...). Thanks !
