You guys are fricken nutz with your challenges . Sure, I can do it, I have managed to do each part succesfully seperately, but all in a row, thats way out'a my league .
The hardest part is the first wall - I have only managed to get past it twice! Once using the proper (I assume the way you expected us to do it) ledge-boost-thingy off the light pole, and once by actually jumping 'around' it (that was a fluke ).
For anyone who can do it all in a row, fitting it all in a rep is a fair challenge - you'd have to do everything perfect and always running. I just did an attempt where I did the whole run succesfully, starting from 'after' the first wall and going all the way to the end - I had ghosttown on and cut the replay right before starting it - And my replay was 781kb (out of the max possible 781 lol).
Good luck dudes.
EDIT: All that said, I still may try it for a bit
