My A320 FCOM says:
"After a bounce with an A320, the spoilers remain extended if you leave the thrust levers at idle. Idle is when the thrust levers are below 3 deg, and below 15 deg when the radio height is below 6 ft.
In case of a light bounce, maintain the current pitch and complete the ldg, while maintaining the thrust at idle. In case of a high bounce, initiate a go-around.
In either case do not try and soften the second touchdown by increasing the pitch attitude."
People that suggest otherwise, please contact Airbus and tell them you're well thought out procedure, so I can use them in the future
