Congratulations on your new Speedy 20! I love my Speedy 20 in monogram that im considering to get the ebene, but i have the speedy b25 in ebene so im really torn. I used to have and love the Nano Speedy but eversince i changed my phone into the Pro max, i couldnt use my nano speedy so i decided to sell it and get the Speedy 20. I love it! No regrets. The Nano Speedy old version can fit a lot except for my huge mobile. Love them for everyday. My go to bag nowadays. As for the lock, i never hang in my bags, it just heavy and gets a lot of scratch. I guess you can sell if you dont plan to use it. Even for the strap of the speedy 20, its quiet heavy so i use a monogram strap that i bought separately. Anyhow, Love the speedy. Congratulations!
