In reply to DSM: I have lots of experience with MicroSpikes, I'm a keen fell runner and winter climb as well.
MicroSpikes are great for running on the fells in winter and with an axe you can get up some quite dicey stuff.. BUT, they aren't for winter climbing, even on a grade 1 snow gully, you might get high, but then a little too high to get yourself in trouble.
If you want to climb easier winter routes, light style, then use a flexable point crampon, like Kahtoola KTS, Camp Magics, of similar, as at least the spikes will give you some traction on steeper ground.
I was testing some Tricouni TRIGS, yet to come to the market place, but on an ascent of the NE gully on Catstye Cam I had to add MicroSpikes for more traction.. had I had KTS, then it would have been ok... but this is all down to experience and had I slipped, well I would have been moving pretty fast to the valley floor.
Running shoes and flexable crampons means no solid base and therefore no frontpointing at all.
Helvellyn is easly possible with MicroSpikes and an axe under winter conditions, as long as you have the knowledge to do it...
I'm not advising it, but there is a little info to help you with your decision.
Have fun and stay safe
