The 804RC2 3-Way Pan/Tilt Head is 20% lighter than its predecessors due to the use of Adapto Technopolymer material. It also features improved ergonomic design plus a counter spring system. Built into the forward/back tilt axis is a fixed spring that helps to absorb the shock of the full camera weight from crashing down. The spring also makes it easier to position the camera on this axis since it opposes some of the camera's weight.
The Oben TS-100 Tripod Strap with Quick-Release Loop and Spring Lock has a QR loop on one end to hold your tripod's legs together, and a spring lock on the other end for attachment to the top of some tripods supplied with a ring.
