any move that causes spin or knockback to juggled opponent will wallbreak. usually every moves that Spark will Wallbreak, but not all of them.
for example: Bryan 1+2 - Feng b,1+2 - Paul Deathfist - Yoshi ws2
and if the theres a string that do spin or knockback like Hwoarang bb+4,3 or Paul qcb+3,2,1 will result in Double Wallbreak. keep in mind that the string have to be fast if the string is slow then it will only do One Wallbreak. a good example for that is Lee b+2,4,3 this string do 2 spins but because the third hit is too slow the wall will break before the third hit connect so it will do One Wallbreak.
