After getting a s623H, you can do either of these:
ws.5M 669 s.63214M/s.5H
ws.5M 9 s.63214M/s.5H

s5H FC is safe from 4f reversals.
The dash jump one nets you a sideswitch, which can be useful against someone who's just mashing backdashes, or a DP, so if you were wanting to command grab, it'll probably be more useful, at the cost of being a bit harder to execute.
The regular, forward jump one doesn't get you a sideswitch, but the command grab still hits, the s.5H still hits meaty, and still catches backdashes, you just don't get the added layer of security from a sideswitch, but it's easier to pull off.

Depending on your preference, you can do the dashjump, or forward jump first, and whiff the s.5M after, it doesn't matter. Up to you
