Definitely not winning at life with this lol, it's actually frustrating because the cables are
so similar. One has a higher speed, one has a higher power, one is shorter, one is longer, one is more flexible, one has a display showing when it's connected, etc... and in many cases it's hard to tell which at a glance so it's always a pain trying to figure out if I'm using a cable unnecessarily somewhere and unnecessarily buying another one because of that.
Charging is an interesting case, I actually deliberately use crappy cables for that too, depending on the charging time I need!
Re: stiffness: I mean I guess it depends, how big is your bag. I'm thinking like a freezer bag not a grocery bag. I could bend them to fit but then I'd probably mess them up.
