I pulled off the one where he jumps from the building in front of the Hotel onto the sign then up on the next level. Took me about 20 tries and I can't do it consistently enough yet to use it in game. The one where he gets onto to the building behind the flag, I think you might still be able to do in 1.41. I almost made it but I keep stalling right on the ledge and falling. I think with a little more practice...

Thanks for the karma, and I plan on learning all of them eventually.
