There is no Hans, at least not the one some bot used to spam this thread. You are making a very good point regarding the release angle of the deeper pumps. The Naish big pump is pretty good though, mine failed after the thread of the top part started popping.
I have a little trick to speed up pumping:
1. from the inflate valve, cut off the PVC lip that connects the plug to the side of the valve edge. Make the cut clean, use a nail scissor. The plug remains connected to the velcro security tab.
2. use the large nozzle on the pump hose and put it OVER the inflate valve.
Now you’re pumping through a hole roughly twice the size. That makes a big difference!
The trick is from an old Naish manual.
Using the big nozzle on the deflate valve is not recommended as the valve can stretch and may cause the valve to pop.
