I think this is what I'll end up doing.
At this stage I am leaning towards a 25 mm. Because it is a tad wider than the 23 but also I will be able to use the same inner tubes for roadie and commuter. I bought a bulk pack so the idea is I use the same stock. 28mm and above I believe generally require a different tube.
