Lots of people have spoken well of this tire and I'd like to give it a try, but I do ride some gravel trails and there isn't much tread there. Do you think this tire would be fine in a 700x38 size for some gravel?

And while I'm at it, does anyone know the best place to get them in 700x38? Seems like they're ~$50 on Amazon and I can't really find them elsewhere. My LBS doesn't have them, could order them but I'd have to want to wait a few weeks, and said they'd be $55+, which is more than suggested retail. I'd rather not go that route.
