Not even sure Uprockets is really that great of an anti-air tbh. It's not something you can just bust out. Like everything you have with her, it's pre-emptive.
I like HT regardless of how much salt I can pour down people's ears when I lose with it. It's been explored a bit and it's as you said. Run cancels allow you pressure, not-RCing doesn't give you any disadvantages (you're + or at the very least safe on block if they block df2). The problem with HT is that you have to get in, and unlike FA you have no real way of forcing them in via projectile.
