Don't know about insomnia, but the usual beta for urban raptors is rather hard. Instead of doing a heal hook and simply powering your way trough it, you can try getting your feet as high as possible with your right hand in the rail. Now the trick is to use a tiny knob to the left round a small corner for your left hand. There is another (even smaller) one a bit further up that you can hold on to while you hold the sharp blade with your right hand, now from here you should be able to step (quite high) onto the rail instead of doing the powerful/painful heal hook thing. If this works for you a beer would be appreciated
