I am going to be doing some light credit card touring....5 days down the Ca coast
but also want to use it for commuting to work...
I am looking at the the Jandd Rear RackPack II and the Carradice probably the Nelson.
Also looked at the Lezyne Trunk bag and Topeak, but I think they are a bit too small.

I was looking for opinions on the best way to go. Any good/bad things about one or the other?

thanks
