In reply to alexgoodey: Most of my kit is all pretty mainstream however there are a few bits of gear I do have that are slightly less common...
Kong GiGi - still the most user friendly guide plate around.
Petal Freino carabiniers - stupidly expensive but superb when paired with a GriGri.
Grivel Plume screwgates - bought on a whim for scrambling but they are rapidly moving to my normal climbing rack. Crazy light but still perfectly usable.
Mammut 180cm slings - I find these a brilliant length but being completely non-standard generally they confuse the hell out of my climbing partners.
Plus, I just bought a Grivel Rotor krab yesterday. Time will tell whether it is a genius idea or just extra weight and a waste of money.
