depend on whether the char is lit, med, or heavy.. and also depend on how soon u input the db frc motion as u catch the opponent with dash, k,[8]. if u are practising on light char such as baiken just aim it so the dashing k catch baiken deep to make sure the k come out after the frc. other than that i'd suggest u try with p,s,k,s,d,e version if have trouble with the ksks variation.
hope this helps
