5a>6b>iad jD>6b>iad jD>5d
the key is you need to jump cancel 6b into air dash, and air dash cancel usually with barrier then jD... it's easier this way since if you air dash cancel with jD it's easy to get j4d by accident
the other key is you can't have too many A hits before it otherwise too much proration and they will tech at 5d usually
