2nd bomb combo consistency help

Hi folks,
I am having a lot of trouble landing this combo consistently. I can make the moves come out of the last raida only connects maybe 10% of the time. I see tourney footage where they land it pretty much every time. I can’t recall seeing it whiff in any footage I have seen. Here’s the combo:

LP > MP > HP x light ex kunai x 2nd vtrigger - walk - light raida x medium command dash x light raida

again, the last raida whiffs most of the time for me and is not reliable.
all tips appreciated

LP > MP > HP x light ex kunai x 2nd vtrigger - walk=>i think this should be dash i think? - light raida x medium command dash x light raida
i do ex kunai 2nd vtrigger dash raida command dash raida so maybe thats it?

yes, my mistake was that i was walking instead of dashing, it is very consistent now, if i f it up its just because im not fast enough and i know how to fix it
