Help!!! Should I Switch my Red Epi Speedy for a Red Epi Alma?

No - by all means keep the speedy! It is far more versatile, you can get more stuff into it, and when you open the Alma to the full, things tend to fall out.

Epi Speedy bottoms don't sag (Almas' don't either), they are quite stiff and have a leather ridge in the middles that works as a reinforcement.
