The trigger problem is actualy a lack of feature. The adapter thinks the triggers are digital buttons so even slightest activation on the analog sliders counts as button press. I solved this myself by opening all my controllers, tightened the trigger springs and cut 1 mm piece of trigger movement limiting plastic off. That way the springs push the triggers further out preventing unwanted slider activation.
Playing brawl fine and dandy with these adapters now.
