I'd stay away from the extra light versions unless you pedal in the flyweight category.
Depends a lot on what you mean by "gravel". I ride the C&O Canal Towpath between Georgetown & Great Falls on Hetres with EL casings several times a year and have never had issues and I'm no flyweight at 0.1 tons. Here's what its surface looks like. No big rocks, nothing likely to damage sidewalls. Your Gravel May Vary...
