They added recovery frames on 2up4. You can easily, even delay jump into your x ray... completely pointless to use x ray though lol. But with this new thing and the horrible demeaning universal Nerf to 34 I'll be using the 2up4 way more because it was practically useless pre Nerf to tanya. Though I use Pyro now and that got a well needed buff.... but still only 1 variation specific string for Pyro they could of atleast gave us 1 more string.
