I only ever use latex tubes. They are lighter, take less space and seem to roll smoother than butyl tubes. Some people think they are difficult to install and lose air quickly. The first one depends highly on the skills of the person installing them. The second, I inflate my tires before every ride anyway so thats not a problem for me. I'm never going back to Butyl again...

It's just a myth that they puncture easier! Whatever goes through your tire will puncture your tube, doesn't matter if its butyl or latex, lightweight or thick.
