If you're getting balloning that's just simple pilot error. Go easy on the up elevator and let the plane settle in. Bounces usually indicate that you stalled your wing by losing too much airspeed. That's common on windy days. You can save a bouce landing by goosing the throttle after the first bounce, giving yourself some more airspeed to work with. On windy day landings, leep a little bit of power on until your wheels touch. When the wind is high, you actually have to fly the airplane all the way to the ground with the power on, setting it down with the sticks.
