I do find it interesting that folks commonly use 9mm or even 8mm as their main line, but are saying 7mm is too small for a cowstail. And for those who blindly believe that their dynamic cowstail is going to save them during a "fall", I hate to tell you that 1 or 1.5 ft of dynamic rope is not doing a damn thing. Please show me the bodies that prove me wrong.
And what situations are you putting yourself in during normal caving SRT that you are taking a fall of 1 to 2 FF?

greater part of the energy from a fall and in various identical set-ups, it has been demonstrated that
the shock loads are inversely proportional to the fall factors (see p. 3213).
"Despite this we should continue to teach that cavers should not position themselves above their anchor point when using
Cow's tails; fortunately this is a situation which is quite easy to identify.
Dynamic rope is designed to stretch over length, and 10-14 inches is not much length (well, depends on what we are talking about )
Also I find it interesting that Petzl makes a sewn static cowstail, which preforms the worst in all tests. Yet, where are the lawsuits involving injuries or worse due to their correct use?
