Plink Dashing on a pad

Classic Fighting Games Ultimate Marvel VS Capcom 3

Hi, im new here. Can anyone assist me in learning to Plink Dash on a PS3 d-pad?

2

Plink H (circle) to L+M+H (should be R2 I think)

3

I set my dash to R1
It feels so much easier for me

Like the above, you press circle, then R1/2
Practice more to get consistency
