Rip Torn
ALL I HAVE IS THE GREEN.
Not only is it character specific AND string specific, it's also location specific (meaning corner vs midscreen).Ducking the tonfa on the way back doesnt work against every string. So it needs to be explored a bit more. Maybe it's character specific too.
I tested both f2~ex tonfa toss and b1~ex tonfa toss and here are the results concerning the second hit of ex tonfa toss:
Shinnok - f2 always whiffs everywhere, b1 whiffs about 75% of the time everywhere.
Kung Lao - f2 and b1 work everywhere.
Sonya - f2 whiffs about 80% of the time midscreen, always in the corner. b1 whiffs 50% of the time midscreen, only whiffs point blank in the corner.
Scorpion - f2 always whiffs, but b1 ex tonfa hits about 75% of the time everywhere.
Sub Zero - both randomly whiff but f2 ex tonfa can always be ducked in the corner while b1 ex tonfa randomly whiffs.
Mileena - both methods randomly whiff about 66% of the time, f2 method always whiffs in the corner.
Cassie - both methods work like 95% of the time!
Jacqui - f2 always hits midscreen but always whiffs in corner, b1 whiffs about 50% of the time anywhere.
Kung Jin - f2 hits about 80% of the time, b1 always works midscreen, about 95% in the corner
Kano - f2 hits about 85% of the time midscreen, always whiffs in the corner, b1 works about 99% of the time midscreen and always works in the corner.
Reptile - f2 whiffs 85% of the time midscreen, always whiffs in the corner. b1 whiffs about 70% of the time everywhere.
D'Vorah - f2 always whiffs everywhere, b1 whiffs about 60% of the time midscreen, always whiffs point blank in the corner, but never whiffs from a half step back.
Tanya - both versions whiff about 50% of the time everywhere
Everyone else it should work 100%. I tested b1 because the second hit is an overhead, forcing them to stand block and giving them very little time to crouch block the first hit. Somebody could test the 34 string if they feel like it...
