Back to pumping ! M cups were filled some years ago, now past 2/3 of L and slowly filling them, then finishing my routine with a few minutes of blue "120 ml" cups (I would have ordered contoured XL from NB but they were discontinued and I don't need the more expensive airlock ones since I already have 2 hose airlocks). Nozzles of blue cups are smaller but I found some smaller hose and a Y piece that fits both internal diameters without leaks.
