Drac, don't get me twisted: As I get more comfortable as a Feeder driver, I will find time to teach myself how to do a hero hookup. That seems to be a good way to save time and be efficient, like learning to recognize when you should walk off a stop rather than drive/back to it, or getting ground off with air (maybe even some non-air stops as well) while making the air commit time.
In fact, I intend to see if the training and experience I received pulling and backing dollies with tugs while working in the PHL air operation will allow me to back up doubles and maybe a set of triples (not to brag or show off, but the skill could come in handy).
On 2nd thought, I was rather poor backing a three train of dollies, so no triples (although the principles on how to do so I understand).
