No more difficult than the double back jumps on the top girder (andrew gardikis jumps?) or the top shelf, I died a good bit in the beginning but have it down pretty solid now. I'm at a point where I'll regulalry incorporate it into my barrel boards, a solid place to use it is right at the beginning of a barrel board (2nd girder long ladder) while waiting for the fire to climb and then I'll use it on long ladders in the transistion provided it does not interfere with normal grouping. 5th girder is where it comes in handy though, cash in on those single ungroupable stragglers.
