Will you consider other wheels and how much do you weigh? And are you leaning more towards aero wheels or light wheels?
Heavier riders will want stronger wheels. To make a wheel strong you can get a stronger rim, higher spoke count, or most importantly, quality hand built wheels.
Mavic and Easton make goods wheels. If can afford it, I think handbuilt wheels by a good or professional wheel builder will be better and last longer. You're also given the option to customize your wheels a little bit.
Since you're not racing, I think durability should be your main concern. A lot of people recommend the Open Pro Rims with Ultegra hubs and DT Swiss spokes (32,32). It's a good combination for a durable wheel but at the cost of weight and some aerodynamics. Kinlin Rims (27 or 30mm) with hubs (White Industries?) and spokes (CX Rays?) (28,24) make a good wheelset, but may cost a little more.
