OK so after months of searching I got the vinyl cabas today!!! Will post pics soon, found her on eBay - and love ! BUT i am now really liking the new Rock, the large size, do you think I can justify having both? Does anyone need two vinyl bags?!! Are they different enough? Really need everyone's views on this as don't know what to do - i am on the lists for the rock and will prob get next week. I of course am keeping my cabas, but just don't know if need both..... HELP!!
