I love Levi 511s. Great cut for people with a skinny build, but have legs that are too swoll from cycling to fit into the super skinny stuff like the 510. Since you liked them in the first place, why not try finding a local place with more that you can try on?

I got my at the local Urban Outfitters (flame on, but they have clothes that fit me well, so why not?) for like $30.
