Like if I go for st.HP with Chun- clearly I'm doing it around max range of the move... which is the range someone could jump at you with a crossup.
I wouldn't argue that xrd is devoid of randomness- it has it'\s fair share, but sfv feels like randomness can swing the result of any given round at any given time much more readily than in xrd.
That's generally the tradeoff with the far reaching moves is that it leaves you vulnerable to jumps.
If you watch top players, they usually rarely swing around heavies, opting instead for mediums, unless the heavy attack in question is fast enough to take risks with like Chun's sweep in SF4.
