Hi everyone - thanks for the advice and different opinions. It’s all useful food for thought.
First of all - yes I’m at 60 jumps, I’m a total n00b and a greenhorn. The only thing I know for sure is that I don’t know anything about skydiving! That’s been drummed into me and I believe it. My instructor has thousands of jumps under his belt and instructs for a living. I don’t question his advice, and while I understand there are differences of opinion about emergency procedures, even among experts, I would never discount anything he says. However, I do reserve the right to source a second opinion on everything I am told, and this is right and appropriate. I’m not the sort of person who unthinkingly follows instructions, or always accepts what I’m told at face value. I suspect most skydivers have similar mindsets.
