I'm trying to get this combo down cS > fS > 236D, 6H > H, dash > 5K > 2H (1 hit) > 6H > H, dash > 5K > 2H (1 hit) > 6H > 236K > 214D, cS > 2H (1 hit) > 623D, 22x and I'm having a lot of trouble getting the first dash out also is there any difference between 6H > H and 6HH? Can I just keep holding forward after the first H?
