I am with Centaurus here! (After all he did teach me!)
Throughout my PPL and CPL training I was always taught to make a go-around if the landing was looking shady!
It was only when I did my instructor rating (and I was taught by VERY experienced aviator), did I fully understand and felt comfortable completing a landing that I would have normally done a go-around.
In this industry we are not only concerned about cost but also safety.
Learning the correct method to handle a bad situation can only make us ALL better pilots!
