Yup, seen the same video too, good ol Rick Beato. You will notice a little difference once you get up to say...11's, but the price your hands pay isnt worth it. That reminds me, another guy who is kinda in the same boat as us: Tony Iommi. You probably already know about how he cut his fingertips off in a machining accident. I believe he uses 8's in standard and 9's in lower tunings. So there ya go, the dude who wrote the Ironman riff uses 8's. Go figure.
Do keep in mind if youre used to playing heavier strings, you'll have to change how you grip the neck when you go this light. That is to say, no Kung-Fu death grip is required. Once I made changes there, I rarely break a string. There is the possibility of when you fret a note, if you have a hard grip, you can push the note sharp just with downward finger pressure, so you may find yourself using a lighter touch with your fretting hand.
