I'll stick my oar in with a vote for the wrench force mini road, and some words about a couple of others:
Blackburn airstick
I had one of these short fat double-acting pumps, and it worked well until its valve springs rusted. They compress air on both the in and the out parts of the stroke. Air enters down the shaft from the handle to the plunger where ring valves allow it out to the chambers on either side of the plunger. Air compressed by the out stroke makes its way to the head through the double skin that makes these pumps quite fat for the amount of air they move. The out stroke is almost as hard as the in stroke, something i found slightly awkward. I liked the pivoted handle.
Specialized air tool
Smart looking, single acting pumps. The slim bodies of the road and mini road versions promise high pressures. I've used and dismantled the road version, and looked closely at the mini road ones in shops.
The mechanism for locking the handle to the body for storage interferes with pushing the piston all the way when pumping. This makes them quite inefficient at high pressures as a significant volume of compressed air is wasted on each stroke. This can be fixed by removing the locking tabs if you intend to keep the pump in your bag.
I liked the slimmness and long stroke of the road air tool, but, without a compression lever, i found its rubber connector fiddly and unreliable.
The decals seem to be soluble in sweat and suncream.
Wrenchforce mini road
A slim pump with a slightly 'value' appearance. Double acting, but with roughly the opposite air flow to the backburn pumps, and the better for it. Air enters through valves at both ends of the cylinder, and ring valves on the plunger allow air into the shaft, from where it flows down a thin axial pipe to reach the head of the pump. This is a slimmer arrangement than the blackburn, and there are no springs to rust. The out stroke is always significantly easier than the instroke, partly because the volume of the shaft into which the air is being forced is increasing as the axial pipe is being withdrawn from it. I think the stroke length is a little longer than the blackburn i had too.
Perhaps the out stroke is so easy as to not be worth the complexity, but in practice i've found this pump effective and (so far) reliable, and the internal design is much neater than the blackburn.
This pump has a pivoting handle like the blackburn, and a connector with a compression lever that rattles. I fixed the rattle with an elastic band, and this i my favourite pump so far.
