The 86 IM is Classic. Shifting onto that 32 cog is not going to be as smooth as the others. Find some quiet flat road and shift through the gears while riding and watch what is going on back there. Your first pic shows an add on derailleur hanger while a later one does not??
Even spoke tension is important for durability and, in my mind, ride quality. Adjusting spokes to center the rim without taking into consideration the tension usually makes the tension more uneven. Read up on that. And regarding rider weight and wheel building, I believe heavier riders need stronger rims and more spokes -- not more tension.
oh, here's a picture of mine.
