Rooster/Capricorn and Monkey/Aquarius meet at 73-78%, a cross pairing of composure and curiosity. The unflappable climber who swears by strength of character meets the tireless dissector who loves nothing more than a good shock.
Monkey/Aquarius pokes at everything to find the root cause, and Rooster/Capricorn is the rare partner whose calm does not crack under the poking, which the Monkey finds irresistible. In turn, the Monkey's inquisitive sparkle is the entertainment the work-ethic Rooster would never buy for itself.
Monkey/Aquarius asks impolite questions for sport; Rooster/Capricorn answers evenly and files the interesting ones. The Rooster's measured pace can bore the Monkey, and the Monkey's intellectual self-indulgence can strike the Rooster as time wasted.
Friction comes when the Monkey's shock experiments hit the Rooster's civic dignity in public, or when the Rooster's simultaneous heap-climbing leaves no evenings for play. The Monkey deconstructs; the Rooster consolidates; both think the other has the priorities backward.
Rooster/Capricorn learns from Monkey/Aquarius that taking things apart is how some people love them, and the Monkey learns that knowledge hoarded for entertainment pays better when built into something lasting. Curiosity gets a career; composure gets a spark.
At 73-78%, Rooster/Capricorn and Monkey/Aquarius have good chemistry between opposite metabolisms. Durable if the Monkey respects the ledger and the Rooster leaves room for mischief.
