Wheels
1. Easy to draw
2. Slowest configuration
3. Easy to tune

Dual Cams
1. Hard draw
2. Fastest Configuration
3. Must be timed for optimal performance

Single Cams
1. Moderate to easy draw cycle - Liberty is touted as having an extremely smooth draw
2. Moderate speed
3. No need to synchronize the wheel and the cam, but the cam has a timing setting in relation to the limb that should be maintained for best performance
4. A nice combination of the benefits of wheels and cams
