Dolan or leader??

If you're worried about comfort, get bigger tyres and run a lower pressure, your performance won't get affected.

Also two brakes on fixed is hugely underrated, fantastic for long centuries ride and actually provided a bit of comfort on your legs.

Noted. I'm no hipster aha, and i know what tired legs feel like, so skid-stopping won't seem appealing at all. As to the larger tyres, that's something i hadn't thought about, you reckon 28c's would provide a good balance? I'm currently running 23c front and 25c back on my steel frame.
