I was gonna get the c1.12, but Dmitry at Triton got an OEM dealers email from pinion that they had a few orange P1.18s surplus to an order from a manufacturer, so I got about 30% off in the end.
It is heavy, 2.5kg for the box alone, but it's low and central. I love the really closely spaced gears (11% between each gear) and 17.5% on the 12 speed seemed a bit large, fine for off-road, but I do a lot of road sections to connect things up, and having basically 4 granny gears make steep climbs a lot more bearable.
My gear range is also huge, granny is 15.8 inches and top is 102.5 inches.
