As stated, I like the one for my short bridge, and the Longhorn Agile for my long bridge. My designs are captured here: jrbtreeclimbing.com/content/bridge/
No problem using it as a main bridge, however... most folks prefer that their main bridge will cinch tight on their Bridge Loops exactly where they want it. This will float around. Also, if this was my main bridge, I probably would go with a more substantial cord like a quality 7 or 8 mm cord.
