You want to be careful though. Sometimes when you come into land you will want to make sure that it is centered. This may require you to increase left rudder on final's but it will make everything proportionate in the flare.
I had a go in a single engine turbo prop the other day and the pilot said that it's one of his last checks is that the rudder is centered not selected for slight left rudder. Especially important if a go around was necessary.
