I used Blackburn lowriders and a handlebar bag for years. Last year I finally bit the bullet and bought a full sized Surly front rack. I still feel like it might be overkill but I am sure glad I did it. The extra platform and stability adds a lot and I can carry more when I need to. I have since added a Wald basket to the top platform which makes it easy to stock up on groceries for the night, before getting to my daily destination.
