In reply to pottsworth:
It's strange, but one of the nice things about the V Twin is that because it is steel then it dissipates heat much better than equivilent aluminium alloy devices.
We tested this on several long abs in the Slate quarries during the various stages of testing the prototypes - it stays a lot cooler than similar aluminium devices.
In terms of strength the device is about twice as strong as a Bug in a pull test. It is a bombproof bit of kit that flys through all the proposed new tests that are being drawn up by the UIAA at the moment.
