My roommate went with the skinny sized ties, because that’s the style he prefers. I would personally maybe go with the regular sized ones. Regardless, your tie width should correspond to your lapel width on your jacket. So, if you’re trying to decide, use that as a determining factor.
Sorry, I don’t know exactly which of the gray ties he got. It’s tough to tell from the photos on their site. If I had to guess, this one.
