I dropped chutes for 3 months over East, out of a 206. Every weekend, usual grind of Saturday drops. Only twice did I refuse to drop, the first because the 2nd radio wasn't operating, so a replacement was found, problem solved. The second, it was 8/8 at 7,500ft. Operator trying to get me up over it but I told him either we land, or we drop from 7,500ft. So we landed. Much to his disgust, but he saw me reasoning for it later on.
Those were the only 2 problems I ever came across. I was lucky in that the owner of the DZ and other skydivers involved there, were quite good in that they followed the rules as much as possible, and didn't make life too difficult for myself.
If you find a good parachute operator, all good and well, but dodgy ones are just way to dangerous to tolerate. Throw in a report, and encourage others to do the same.
Certainly enjoyed my time dropping meatbombs, and learnt a hell of a lot from it.
