Still no opinions? Lame :P
I tried to incorporate the second combo into my game in the past two days and it did pretty well. Imo it fills a little gap for having 100% meter post 3(B) which makes the move even more versatile. Gives you an option for pretty much every amount of meter:
0% meter: 3(B)~SCH K = 39 dmg
50% meter: 3(B)~SCH K BE~iaga = 76 dmg
100% meter: 3(B)~SCH K BE~2(B)~SBH K BE = 96 dmg
150% meter: 3(B)~SCH K BE~CE = 108 dmg
Edit: A little bit more insight about the teching.
3(B)~SCH K BE~2(B)~SBH K BE can only be air teched with: forward left and backward right. When the opponent techs left or backward left, it will only partially connect for 78 damage.
3(B)~SCH K BE~B6~3(B) connecting, doesn't depend on neither range nor ukemi.
However it is a char specific combo and works on specific air teching directions. Out of the ones that i tested, it didnt work on leixia and mitsurugi and it worked against tira and asta
for the following air tech directions: none, forward, forward right, right and backward. It actually covers more than i thought.
