good call. It is a stronger wheel as well. Also, by being a full-face wheel, you can install wheel weights closer to the lip area, which means the balance will be easier to get right, and more accurate.
The Nurburgring can also be made in 22", still weighs right about 30 lbs.
another light weight is the Giovanna RL series of wheels. Awesome options there too, in 22 or just 20".
