Hi jags and in4. Yes, the Sterling can be a feel a bit heavy on the hills at times but where we live it's quite flat. It is a comfortable ride. When I bought it I had plans for touring but for a variety of reasons that never happened so it is never loaded. In fact I am looking at increasing the size of the chainring because I feel the gearing is a little low in daily use. I have Conti Town and Country 2.0 tyres on at the moment. I am amazed that the Kirtland bag has survived for so long. Black has faded to grey and everything feels a bit brittle but the zips still work smoothly so I don't feel the need to change. I am very happy with the Sterling and run her together with my 20+ year old hybrid Dawes Mean Street.
