just on pumps has anyone ever come across a pump that does exactly what it's supposed to do, pump up to 80psi 
i know i havent.
jags.
The two pumps I have for my road toolkits will do 80psi, but I don't need pressures that high on my Thorns. I have one of the Lezyne mini-pumps with an old-fashioned flexible hose connector - that gets my Brompton tyres up to 85 psi and has been lent to "racing" cyclists to inflate their 700C x 23 tyres up to high enough pressures to get them home. Downside is it needs a lot of pump strokes for fat tyres or very high pressures.
For long trips I have a more sophisticated and heavier Lezyne pump, with built-in pressure guage that (sort of) works like a floor pump. This is more comfortable for inflating 26" x 50 mm tyres. I used that on my Spain trip, but I will probably take the smaller pump next time as I get very few punctures on 26" tyres and am now on butyl tubes that need less topping-up than the latex ones I used until recently.
Both pumps in my road toolkits are less convenient than the old German track pump I keep in the garage, so they tend to get more use on other peoples's bikes than on my own...
