thanks posh totty so would anyone bother with walking poles in lowland walking in snow or just stick with crampons etc and leave the ice axe to snowdon or ben nevis etc
Yes, I often would. They can help provide a lot of stability and as folk have said, unless you are likely to be on a slope where a slip would really need self-arrest, can be far more use than an ice axe. (I have self arrested with ski-poles once but I wouldn't want to make a habit of it
).
Actually for a bit more security you can get poles which include a foldable 'pick' in the handle to provide you with something that could be used for self-arrest - they're aimed at ski-tourers but might be a good compromise for the type of walking you describe where a full axe is probably redundant a lot of the time. Grivel do one, and I think Black Diamond may do too.
If you go for crampons rather than something like Microspikes, I'd still be tempted to take a look at Kahtoolas, either the steel or alloy ones - they're light and pack up small, and you'll be unlikely to need to rely on the rather short front-points.
