Thanks for the advice, in the end after a lot of online research I ended up with a Birzman mini track pump (https://www.sigmasports.com/item/Birzman/Horizons-Apogee-Lite-Mini-Floor-Pump/PU26) which will fit in panniers for commuting/rucksack on long mtb rides AND hasn't unscrewed or damaged any valve cores so far! Highly recommended if the size suits your needs

I've used the Air Support a fair bit during testing and i've not had an issue with it unscrewing valve cores. Just be sure not to over tighten the valve head and make sure that you valve cores are fitted securely!

I have a lezyne that has the annoying design quirk of removing valve cores when you unscrew the hose. Is this desig likely to do the same? Cheers

Lifeline and/or Truflo both do a very similar looking pump but with a thumblock mechanism, guaranteed no valve core unscrewing!

People will just tell you to loctite your valve cores or carry the wee tool to tighten them, I'd prefer a design which just didn't unscrew them in the first place! Don't know why 99% of manufacturers have gone down the threaded route...
