Last week I received my first two-stage (4x5x10) and a straight 2.5-inch cock cylinder. It has been great fun experimenting with these and trying out different pump combinations with other tubes.
One of the things that has surprised me is how different pumping in a two-stage is from pumping in the ASTJ. I half-wondered if it would be a waste of money but now I know the answer is a resounding no.
These pics are my first of the two-stage and there are a couple of cylinder pics here too:
