I read that article too, and I must say I thought it was straight out of the traditional "wear big boots or you'll die" school. I thought it was fine at the extremes (Yaktrax for the park and B2/B3 for grade3 upward), but it bore no resemblance to my experience of the 'middle-ground' inhabited by microspikes and flexi crampons with B0/B1 footwear. I'm not saying they don't have limitations but they're far more capable than the article acknowledges.
You call them design faults, but they're only faults if they're not what you're looking for in a jacket.
All the jackets you link to have a serious design fault (for me) - no hood! I wouldn't choose them for any tour because I want a jacket that will function for me on the bike and on the campsite and on sidetrips/walks/town-stops without relying on a helmet cover or similar to keep me dry.
Does that make your jacket choice automatically poor? Of course not - for you. Personally I'd not want to rely on a rain jacket made from Epic cotton that describes itself as water resistant and "suitable for all types of distance cycling in the dry, heavy showers or persistent light rain".
Reviews give people information about an item's features and how well they do the job intended. People make expensive mistakes if they don't work out for themselves what they want from an item and then use the review to see if that particular item fits their bill.
Bad luck there Flaff, but I reckon you took the right decision - wet feet are almost impossible to keep warm in the current winter temperatures... definitely better to have your toes intact for the next walk!
The snow was pretty soft, certainly not icy. MoS used microspikes in places, I didn't need to. The axes and poles remained on the pack throughout. I take Gneiss Boots' point though that Snowdon routes may be more compacted.
The ridge from Moel Eilio to Moel Cynghorion is superb, giving fantastic views in clear weather. There's one particularly steep slope descending from Foel Goch that could be interesting in full winter conditions.
These webcams from the top hydro station on Elidir Fach are pretty handy - as you can see there's a little snow remaining on Moel Eilio at the moment.
The plastic cradle bindings and the flexi bars should mean those G10s will go on just about any boot... I presume you're not planning on doing anything particularly extreme? I'm pretty sure Chris Townsend has reviewed them and reported using them quite happily on a number of flexible boots and possibly even trail shoes.
Cracking day today - we only got out for the afternoon (so came down in the dark) but got up Glyder Fach with quite possible the best cloud inversion we've EVER encountered - I think it stretched all the way to Ireland! Photos may well follow in due course...
