16/24/50 mm or 16/35/50 mm?

I'm surprised no one asked what type of photography you're into and how the images will be used 

If you submitting to image libraries I would take the 24, 35 & 50. Better quality more keepers. 16mm may cause a few problems when viewed at 100%.

If these are personal images and not for commercial use I would go 16, 24 & 50.... well, I would take the lot but that's just me
