I can't provide any decent advice for Axl, but I play a couple of good Leos regularly and I mainly try and FD the pressure once they introduce specials in their strings for a while to keep him from maintaining it constantly.
You can also throw the H rekka (the name escapes me) if you notice they continue to do it in their pressure and I'm pretty sure you can PB it too.
Once you do that a few times, the pressure tends to stop being so suffocating as they need to adapt and find other strings to use.
Hope that is of some use for you.
