Lemme make sure I understand your argument here:
By increasing the mass, we decrease the maximum temperature achieved.
WHICH IS PRECISELY WHAT I SAID IF YOU'D BOTHERED TO READ IT.
I said that we can't simply compare a pyramid with fins to a pyramid without fins since a pyramid that simply lacks fins will have lower mass.
And again, the issue is not of overall heat in the system, it is heat that remains in the device.
And ANYBODY who says that a rappel device shouldn't heat up that much has NEVER done a 60m rappel on dual 10.5mm ropes, much less a fast rappel.
Should I write out the energy in/energy out equations so you can see why a fast rappel would heat up the device faster than a slow rappel? Or can you work that out yourself?
