I'm new to all of this. I have a K3 that will be residing in a case. I've been reading all the posts and am interested in the BB Roo and a Hobo bag. I'm not sure about which size to get. Will the small Hobo hold the roo with K3 and most other stuff a girl needs to carry, or would the medium be the better choice? I got one of the Fossil Sutter large zip tops and it is huge compared to what I usually carry. I needed to go larger to accomodate the K3.

I was just hoping someone with experience with these bags could give me an idea.
Also, will the Roo bag hold the K3 with a e-luminator light and the charger for the K3?
Thank you for any help.
