See a screenshot of this change in action. The upper sentence is how the lead class currently appears. The lower sentence is with the font-weight at 300.
When on a mobile device (iPhone in this case), the .lead body copy class is displayed in a very thin font, which is overpowered by regular text. Kind of defeats the purpose, huh?
I've bumped up the font-weight in order to increase readability on mobile devices. It also wouldn't be a bad idea to bump up the font-size from 16px to 18px.
