I have a co-pilot due to be delivered tomorrow. I hope to use it as a EDC (in place of a briefcase) and a personal item on planes.
I'll have to see how it looks tomorrow - I'm concerned about it being too large for daily use. I really like the idea of the SK, but as a guy, I felt it was too purse-like to use.
I may end up returning the CP and just getting an S19 which could be used in most of my CP scenarios anyway.
