A figure of 8 using proven I beam technology (DMM)
Reduces weight by around 50%.
Good because if you want to carry around an extra bit of kit its better if you don’t notice it.
Increased surface area by around 50%
Great for dissipating all that heat on long or quick descents with out melting or damaging your rope.

Thanks for the enthusiastic feedback. There is a small fillet at the moment but unfortunately the image resolutions had to be very small.
Are you really hoping for sub 40g, with heat dissipation requirements? (my BD super 8 weighs in at 87g.)

Mark, this looks very promising, I especially like seeing the “less-is-more” type of thinking that went into this. The only thing i would suggest concerns edges as a bad thing with rope friction devices. Perhaps you’ve already thought of this, but didnt have the time to image it here, but those nice “I"-beam 90 degree sides should be rounded.
