With the OP/TECH USA System Connectors, you have several connection options. All of the OPTECH straps with clips that connect the shoulder pad to the strap ends are interchangeable. The beauty of this is being able to use any shoulder pad with any camera strap, bag strap, etc. You can save yourself some money on straps by having a couple pads and several strap ends attached to the equipment so you can connect and go. The strap ends also clip together making a short strap of their own so you have that option as well. Personally I leave the shoulder pad off the camera around the house for snap shots so I can just grab the short strap and go.
