PLA/PVA printing on V2 non flexy extruder

Has anyone had success printing matterhackers pro pla (black) on matterhackers pva? I’ve done the fan upgrade on my dual extruder to reduce the heat creep as well as i have a 6in desk fan positioned in front of the printer that i turn on after the first layer goes down. Is matterhackers pva too flexible? Could it really be my pla color effecting this adhesion? Should I try ultimaker pva as it is supposed to be more rigid than most pva?
