We trained on 60' towers, which were supposedly the height that everything looked "high" and that seemed to be the truth. Looking out the door of a bird never bothered me as much as doing an Australian off the towers. We just used two carabiners as brakes and took a double wrap around them using two 1/2" braided lines. We tried the seats out of the same line. While stepping out into thin air on a rope   100' up is definitely a rush, I never thought it was anything but part of the job and didn't see it as my hobby.

At least they didn't come up with Fast Roping until I was out of Air Assault units. That's just freaking nuts.
