Not to start a flame war, but....
There is no really good reason to go full forward on the props for landing. The conventional wisdom explanation is "in case of a go-around the props will already be full forward," but most pilots can look ahead on short final to see if anyone is in position to taxi out onto the runway or there is no small boy with a bicycle or a loose cow waiting to cross the runway. Pushing the props up while the engine is making power makes noise and is objectionable. The airplane will land perfectly well with the RPM at 2300 or 2400.
