Well what metering would you use instead?
Spot metering is fine, but you have to find something roughly equal to 18% grey or you have to use exposure compensation, not exactly the quickest way of doing it and has the possibility to go wildly wrong if you meter off something and don't use the correct compensation, centre weighted will get it right about 80% of the time, you just might need to use some compensation the for the other 20%.
Last time I looked you had a Pentax Super A and a selection of other manual cameras, whats wrong with the centre weighted metering on them suddenly?
