'Upgrading' to skinny tyres pointless for London commuting

I think I'll ride latex... just to save weight.

I'm admiring your individuality here Iain. I'd never really thought of it for cycling before, but I guess well-shined latex is pretty aero though - especially on your arms.

Oh??? I thought that's why ppl rode latex... Why would anyone then?

For most people I think it's mostly the tightness that they like from latex and oddly, also the sweatiness. Many say that it feels like a second skin. And if that's what you like, then you should be true to yourself I guess...
