Price: £25 MegaJul (is made of stainless steel) and the accompanying official screw aluminum (Edelrid) crab. Together £ 25 including shipping.
The switching of the Reverso 3 to the MegaJul is me too big for me, it is (probably) a matter of learning and getting used to it. Anyhow, I got it once used to belay and once to abb. I know the MegaJul is super light and is a semi-automatic. Comes with instruction manual.
