If they usually burst when you RC, then that is your bait right there. RC, wait for the burst and then continue your combo as normal with free pressure afterwards if it happens in the corner you can get a nice shotgun combo going for sure

I think relying on 5HS as your go to anti-air would be poor practice and would leave you heavily baited into being punished by well spaced air dashes. Learning to and applying cS ASAP is probably the #1 priority i could reccomend

I feel SG-P would be better as putting spaces in-between the letters could easily result in confusion of inputs. SG-P rather than SG P looks like one input rather than two to me
