miamijim, I've used your "guide" here for all the bikes I've shipped, two personal and six or seven facilitations. In each case the bike arrived in 100% perfect condition.
The real key here is the pipe foam. One the frame is covered it becomes the solid attachment point for everything else that's loose. It's an inexpensive, safe, and easy way to get a bike form A to B in perfect condition. Lift fork through the box notwithstanding
