I always hear every one said you should customized your break settings, and I'm sure every one should.
But then I read that we don't need two break settings with the Flick (Deep, Shalow).
I understand that the Flick was standard with 5th control line (not any more apparently), so that the forward speed on openning is already reduced by using more surface of the tail.
Now let take the example of a vented/valved canopy with 5th control line (Flick or other).
Why would you only have one settings instead of two Deep and Shalow?

Another side question will be is it reasonable to say that I could have a deeper break setting if my canopy is vented? And then reduce my forward speed on openning...
