I love the colour, Royal & also love the Linear Studs. I love the Darling but have the PH Darling & Ebony Fringe. I have 2 other Royal bag but both are Bright Royals, a studded rocker & the MAM with Brown BW. I don't need another Royal but I love blues. I am not a messenger bag person & have not seen a Roadie but have always wanted one but other bags always took priority. How practical is the Roadie if I choose to side sling it all the time? Will it slide off? Should I just go with tried & tested Darling?
