Ok for debates sake lets leave bow models and companies out of this.

What would you call the benefits of using a soft cam pulling 70 that feels like 60-62 compaired to a aggressive cam at 60?

Lets say they both for arguements sake have the same riser, axle to axle length and specs for both bows, and they are both set at 30 inch draw and a 7 inch brace height.

Would a 70 # soft cam be that much more quiet than a 60 # aggressive cam?
