I own both the Madisons and the Virtues and love them both.
The Virtues: less expensive, comfortable, excellent ratchets, durable, light, very adjustable
Madisons: more expensive, but also look higher end, insane cushioning, excellent ratchets, durable, a bit heavier than the Virtues, very adjustable
Also consider: Ride DVA, Burton Lexa, Union Trilogy
All of the above are excellent bindings. I would look for the one at the best price. I bought my Virtues at REI.com last year for $35!
