you don't have to start the combo with 6hs but it's a very strong starter. You can also do an AA counter hit to get this combo from a bit further away from the wall if you fish for it.

I modified the sideswap to have 5S~2HS HS Dolphin instead so that you can get the wall combo without the dp punish in the corner.
