The Club Tour is a good call Jags. It will do the lot.
But being a little like a jack of all trades it isn't the fastest bike out there but is really comfortable doing it.
My friend has a dropped bar Mercury and I have a Club Tour Mk4. We ride together and we keep up with each other easily enough, but we are not out there for speed. We are both dropped on hills by other friends with light carbon or titanium audax bikes. We catch them up on the downhill.
He also has a Koga with Rohloff which I have ridden and I think is a beast of burden and I am noticeably slower on it.
I think you would notice a difference in speed on all three Thorns compared to your Koga.
I would be asking myself do I want a Rohloff or derailleurs?
If the Koga is Rohloff would I be happy going back to derailleurs. A lot of people can't go back.
If you are happy with both then I'd go visit Thorn and try them all and go on routes that have some hills. All three bikes will be fast on the flat but it's when you get to the hills that you can see difference in speed. Bridgwater is relatively flat, but there are hills, so you need to be pointed at them.
I can feel the agony, most of us have been through it and some still go through it every time a new bike comes into our mind!
