    I've done a little searching, and don't seem to find a consistent explicate answer – is there any consensus on the position of the isolator knob? Should it be closer to vertical? / are there any issues with it slightly past vertical so there is more room to lay your head back? Should it be a bit forward to make it easier to shutdown? --- Or is it just a matter of "if I can perform the shutdown it really doesn’t matter".

    And one further question on the shutdown, and this may seem very petty but... When you are shutting or opening valves, do you use (or is there any reason not to use) your finger tips (That would be thumb, pointer, and middle) grabbing the knob more from the end, as opposed to “gripping” it between your thumb and pointer like you would normally turn the tank on, or grab a bike handlebar. Certainly there would be more power in the latter, though I am not sure if you would ever have to crank it that hard to open or close it. And again the reason I ask is because it would certainly make a difference in the range of position the isolator could be in – in reference to my first question.

    Thanks in advance…

    Isolator is turned down slightly towards your head to make it less likely to impact anything overhead. It is also left loose so it can rotate if it is hit.

    That is how I do it. No reason I can think of that you would have to crank down on it.

    I do isolator tipped slightly back because my head is large enough to have its own measurable gravitational field...

    That might have to change if i start to scooter in caves, but i'll cross that bridge when/if i get to it...

    Lamont, look what you have done now. I find myself forced to agree with JeffG twice in a week. Unless you look like a costumed Disney character, how does tilting the isolater slightly down cause it to hit your head?

    And I never called Canadians strokes. I gave them an exemption for being "special".

    You haven't met Lamont ... the dude owns an oversized melon. If they were to ever make a "Calvin and Hobbes" movie, Lamont could easily cast for the character of Calvin ...

    It is worth it in a random insult generator sort of way. I got a nasty PM accusing me of being the one doing the trolling.
