Poteroo, I would think you have the knowledge and lots of experience, some have the knowledge and enough experience to get the job to get more experience to get the job to fly a airliner. I would rather learn with the experienced and knowledgable as I have done.
As Regulations and red tape are there, right or wrong but while your doing paperwork your not on the immediate task of looking and as far as regulations any mishap is likely to be a breach of regulation. Training is the answer, if people know their stuff, they may be less likely to make poor judgement.
As far as low level goes, the training is important, I do not have a low level endorsement but had a few AG pilot instructors and flew at low level in aircraft and helicopters with very experienced pilots, their job was using helicopters as mobile cranes lifting steel and concrete in mountainous country. Over 20 years I witnessed quite a few mishaps, the most serious were rotor strikes with the trees and engine failure at low level. The important part is they take calculated risks and their experience let them know their limits. Every helicopter pilot I met involved in long and short line lifting was involved in an acciddent at an earlier point in their career, one had two and this was during being trained for long line work on the side of a mountain, he was the best long line pilot I had seen, probably because he knew his limits.
