Running 2.4" tyres, so a puncture means a long time getting any reasonable pressure, and approaching 50 my right arm isn't as well practiced as it once was so fatigue soon sets in. My mini pump - a vintage Blackburn affair - needs replacing.
A quick search suggests either Lezyne alloy drive mini pump or Lezyne micro floor drive HV mini pump. Either needs to fit in a decently large backpack.
Any preference between these, or any other suggestions?
