Jaysus! Now you got the old grey matter working!
White Lion Hill EC4: takes you off Queen Victoria St onto the Blackfriars underpass /Embankment. This is one of those 'Monaco GP' moments....come off Queen Vic St at a fair lick.....90 deg left fast flowing followed by a 90 deg faster right. This is a one way street but has lots of metal walls on either side

have impressed a few of my friends on this one!
Hyde Park Corner onto Park Lane W1: think Julian rather likes this one!
3 lane wide and surfaced with shell grip type stuff. Fast and flowing double left off Hyde Park roundabout and then switchback type flick back onto park lane. Big grin factor when there's not much traffic!
Park lane onto Marble Arch: More of the same....traffic lights permitting.
Either of the exit/entry slips onto the A40 elevated at Royal Oak.
Bishops Bridge Road north bound onto the Harrow Road East bound. Great wide roundabout. Good road suraface where you can easily touch things down!
The new roundabout on the A408 Stockley Road. The cambers are all wrong and the road surface changes through the fast flick roundabout. But there is something exciting about feeling your bike unload and get a bit nervous
Stockley Park Roundabout: Used to be great, but the road surafce has now become extremely worn and shiny. Still good but front can let go without warning!
