I would go for the Mon Mono NF. Its a custom piece that you get to choose the colours, and it will remind you of your special day when you carry it. No one else will have the same colour combination/initials as you.
Whereas the speedy, a lot of people carry it. Yes, its classic, but the Mon Mono NF with your colour combination will not be as common as the speedy.
