Given your height, you are probably going to be limited to WSD purely because of the availability of sizes. What sort of riding are you looking at doing? If you want to ride only on pavement, and want lighter, look at a hybrid or flat-bar road bike (Trek FX series, Specialized Vita, etc) if you don't want drop bars. Stay away from suspension and huge knobbly tires. If you're just going to ride on pavement, it's not worth paying for suspension that you don't need and just adds a lot of weight. Decide what you want to do, and how much you want to spend. Test-riding is going to be hard, because of your height, but I'd at least go talk to some shops to see what they carry that meets your needs.
