Kriega us30 or us30 combo

I am going to be using this bike as a commuter, I work for a sports performance company so I always need my laptop 15" mbpr, workout clothes, shoes, cleats, and misc pens and folders. Has anyone had any experience with these packs? I feel myself leaning towards the us30 combo since it has the 20 and the 10 but on the website the us30 is on the superduke and looks good. If you have used these please advise me. As always thanx in advance.

I have US 20 & US 10. I am using US 20 as a courier bag, it is so right size and comfortable. Last time I flied with Ryanair and had no particular bag for it I used also US 20. It is the pretty universal bag for any life occasion if when you need it, besides motorcycle use US 10 I have used once, but with US 20 it gives nice addition to it; and their straps connect well. However I would not miss US 10 much in case I would not have it; US 20 has the best possible "real use" factor.

I've got the US 20 and 10. Love them. The 10 sits on my tank and fits perfect. Don't need to remove it to refill. The 20 is great for most day to day stuff. And with both together I have all I need for trips away. For me the combo is the way to go.
