Hi everyone! I'm trying to save up for a BBag (I'm thinking a classic Black SGH City) and am contemplating the type of leather to go for. I really like the softer, smooshy leather, but I'm wondering if it's as durable as a stiffer leather? This is a bag I plan on keeping for a loooong time, so although I love a soft leather if it's going to get worn out more quickly I might suck it up and buy a stiffer one. Do the stiffer leathers soften up over time as well?
