I'm almost 100% consistent with the single banana lock if I'm going to the left. For whatever reason, I suck at doing it to the right.
More than anything I'm looking at what happens when I throw a banana from above and try to set up for it. I play Wi-Fi a lot, which screws up timing, so I've only been really able to test that. More often than not since it's hard to set up, you aren't going to get the actual lock, so I'm looking to see what I can do out of a sheilded banana when I'm above, or a spotdodge or roll or whatever, and what characters have the utilts or usmashes or whatever that are good enough to punish those straight on aerial approaches.
