After we have seen, that J3 beats F3 in opposite spin, I decided to test J3 vs F4 (the successor of F3).
Alternating Launches. Moderate Power.
F4.0B.At vs. J3.0B.At
F4: 0 Wins (0% Win rate)
J3: 5 OS (100% Win rate)
(3 Draws)
Well, F4 has no rubber as F3, so it's worse in opposite spin (though my tests showed lately that F4 beats F3 in direct matchup).
Next, I tested the combo suggested by Bladekit with Guard:
B3.0B.At vs J3.00E.Gr
B3: 3 OS (50% Win rate)
J3: 3 OS (50% Win rate)
(7 Draws)
I stopped after many Draws. Guard seems to be a strong driver in opposite spin, on par with Atomic. I dont think it would beat Bearing, though.
