yeah start even smaller that 1/8 maybe. i got 1/2 valves and i got a plug in mine with just smaller than 1/8 hole and it hits the ground from aired all the way up in about a half second. its super fast. when i air down i have to just touch the switch a few times so it goes down in small steps.but i have one dump valve for each bag. if you have one dump controlling 2 bags it will go slower because twice the air has to go out of the same size hole.
