While we're on the topic of Falco's Lasers, I thought that I'd throw in something that I found while practicing Fast-Falling Lasers. I'm not sure if you guys already know about it, but here ya go anyways.
Okay, so we all know that Kirby and Falco can do a short hop and get off two lasers without landing lag. As I was doing that, I noticed something that would happen from time to time. If I started to shoot the lasers just as a jumped, then as I would land (While mashing B into oblivion XD) I would land cancel a third laser with it having no animation or landing lag. I already knew that you could cancel a laser like that, but I didn't know you could do it at the end of the double laser jump. I think it will also work on a full hop, but I mainly did only short hops the whole time so I can't say for sure. So, now you can get off three lasers instead of the usual two with this technique and you can keep doing it many times in succession with some practice. This is a great setup for a F-Smash at close range since the opponent will be stunned by the laser while you hit them with you attack right after wards. It may also prove to be a good technique to keep your opponent at bay and away from you. This was pretty hard to do when I would slide my thumb from Y to B since I would often start shooting too late. But once I set L to jump, it became much easier since I didn't have to move my thumb from B. Again, sorry if you already know about it or if it's pretty useless if you try it out, but I just thought I'd let you guys know.
