This poll is just out of curiousity. This is people's oppenion. This is not an "I gotta better vent than you." Vents are diffrent in other ways. Some may have ATC, some Don't. Some have NIF, P0.1, Vent cockpit, SBT abilities, some don't. Some are loud and abnoxious, Some are not. Some are harder to adjust settings and harder to get around in, some are not. Its your oppenion, I'm looking for. The following ventilator are your choices, and your oppenion. PLEASE don't get into an argument.Which ventilator do you prefer? I'm curious to see what happens.Drager Evita XLServo IHamilton C2Hamilton G5PB840
