Does Size matter?

As the rave scene evolved and I guess printing got cheaper, rave flyers went from A5 to A4 to A3 and then to designs with many pages or folds. Which ones do you prefer? I think the A3 ones have the most impact, but were easily damaged when collected at the end of the night. Plus they don't fit in any of my filing systems as they are so large.... A4 are perfect IMO. A5 just a little to small to get that visual impact...
