Advantage of a Single Anchor Attachment Point HitchHikerXF (with music)

The HitchHikerXF is unique in the world of climbing devices in the way that the load bearing anchor has been combined with the SRT tending point and perfect connection to a SAKA knee ascender.
There is less chance for slack or flop to cause issues.
There is no change that a carabiner would side load. (Captive Eye version directly connected to the bridge)
The connection point makes for a cleaner and less cluttered chest area.About sit-back, I find it not to be an issue.  I make my ascent then sit back, so a few inches out of 50 feet is not significant.  If it bothered me I will take the Swing Arm and move the body up and push the hitch up and illuminate all sit back before I 'sit-back'.  What always bothered me is having slack on a carabiner attachment during SRT ascent,  then, sitting back to discover the carabiner is sideways or reversed or moved in some other manner.   That is my life support and while an SRT device is being tended, for most climbers, it is slack.  Having to use keepers or captive eye carabiners to keep things from being side loaded bothered me.  

The Swing-Arm is designed to be unaffected by being unloaded.  It self orienting, will not go sideways, or have a gate that gets cross loaded.
