you can dash forward and do the st.HP. I just can't get the v-trigger sonic booms to combo into super no matter what I do.
this is kind of depressing though, is every new character going to be ridiculously difficult to play? Reasonable execution is the whole reason I like SFV but it's hard to give a shit about characters I can't realistically use.
most of the combos in those trials are garbage you will never use anyways dude
Just play guile as a solid fundamentals character and you will be fine
