I tried a different 65 area layout for a while that placed the input in that spot between the multibonder and the output, and arms below the assembly instead of above.  It required that the final triplex bond I made be one of the end ones instead of the middle one, and that turned out to have some impossible requirements to get into all 3 positions within the area.  Shame, because that layout had better access and 2 arms so it would be much faster.
