I happen to main BOTH chars. I didn't know about this F33 overthrowing the Tail Grab. Guess that I'll have to practice down the Ice Klone and the D4 to learn his anti-EX ability. I will try this out with all the chars to get used to punish them with the anti-EX ability.
BTW, if so you happen to see Dragon or anybody trying the Low Rush, just stand back, while doing the Ice Klone, because this one the Low Rush can't pass through.
