"weekender21" - that short bridge (below) you use only to rappel down correct? What length is it and did you make it or buy it?

Sterling 11/16" 17mm climbing sling 12". I also purchased a 24" sling but now only use the 12". It works well as a short bridge with my Tethrd Mantis. I use it for the ascent with Madrock Safeguard and on rappel with an ATC and autoblock. Your specific setup, build and climbing experience will determine what you need.
