Ferg I think you are very generous in aswering the questions and at the same time you are a little sarcastic. These words my folk Ferg "How about you do an inspo course or any ccr course with a decent instructor and then ask some sensible questions." could have been writen in an other way and yet to give the same meaning. What you meant to write (I think) is: "probably an Inspo course with a certified instructor would answer a lot of these questions and a lot more in full details" Right?

Being an instructor myself I know that people come to a course with different backrounds and different mentalities. I particularly enjoy a class where people like to ask questions or even to question my opinion as this allows more discussion from which some people do get a benefit! Please do not take it as granded that other people would see the obvious! Because the obvious is a very subjective matter! I mean for some people the answers are obvious while for others are not. It would be a sad day if we characterise a question as insensible! There are no insensible questions! There are retoric questions and real questions. And believe me the worst questions are the ones that we never asked!

Nice answers BTW and excuse my if I was a little philosophical. It is only because I thought...

Dive safe.
