LV transformer selection

happyhero

Can anyone advise please, I am putting 12v LV halogen fittings and the lamps will be 50w. The transformers come in 0 to 50W rating and 0-70w rating that are of any interest in this case, so the question is which would you pick to go with a 50watt lamp?

My mate who is also a spark is saying the 0-70w ones but I was always told to try and load the transformer to max or nearly max.

Any help appreciated.
