I'm thinking
Schwalbe Ice Spiker Pro but at over £120 a set I'm thinking quite slowly

But then again they'd last me a while, as I'd only be using them in full on snow.. I know they do a steel bead version which is much cheaper, but it'd be my intent to travel a reasonable distance so I'd like to keep the rolling weight down.
Despite their limitations I like my winter marathons which suffice for selected routes to work, it's just I'd rather be riding out into the sticks to visit family, friends and enjoying the countryside. Have I convinced myself yet? even though the likleyhood of more snow this winter is low... still I'd be ready for next winter and it's not something you go get the day before the weather changes is it?
