In reply to UKC/UKH Gear:
My thoughts as a keen snowshoer:-
There are two sorts of snowshoes, 'trail' ones and 'mountain' ones - trail ones are rubbish on slopey ground, my wife's just been on a snowshoeing course at the weekend and the instructor who was teasing her about her old, big, 'heavy' Denali Ascents had to wind his neck in when she was happily tromping up and down the slopes and her fellow students in trail snowshoes were sliding around. MSR's mountain range are the 'ascent' models by the look of things. The confidence you get on steep ground is amazing, I feel like I'm some kind of indestructible tank as I go straight up stuff I couldn't do in summer in hiking boots. NB. this could get you into trouble in terms of avalanche terrain, but it gives an idea of the grip you get.
Catching your legs - as a user of old Denali Ascents with a plastic floatation area I can say that it must be the metal perimeter on the Lightning ascents tested that is the issue - much of my snowshoeing is on twisty rough terrain in woods, and over buried dwarf pines resulting in me hitting my legs all the time, and I've had no catching or damage at all.
Size - I'm ~85kg in jeans, jumper and trainers, so easily 90+kg with all my kit (winter clothing, daypack with lunch, emergency gear inc shovel, bumsledge, poles). The add-on tails are definitely useful in anything soft. They can be a pain in rough terrain - where there are shallow boulders, tree roots or other buried stuff making the shoe sink in different depths at different parts of the shoe, or where you're doing lots of turns (e.g. zigzagging up/down a slope), but the rest of the time they're well worth it.
Crampon use - I'm intrigued as to the need to continue to carry crampons, Dan - where do you find the snowshoes don't provide enough grip on ice? Is it because the large grip area results in the teeth not penetrating deep enough (all your weight on dozens of points instead of 10)? I've only come across ice once - on a broad wind-swept ridge where freeze-thaw had resulted in it becoming a sheet of clear ice and had no trouble in the Salewa 999 snowshoes I was using. I can see steep, rocky terrain being an issue where you can't fit the shoes in between rocks, or where the ground is too uneven, but would you want to be wearing snowshoes there anyway? I don't do UK winter stuff, so am just curious and want to learn before I find myself in trouble!
Expense and quality - I'd have no hesitation in buying secondhand MSR snowshoes if new ones are too pricey - my Denali Ascents are easily 10 years old and are still going strong. The straps, however do lose their suppleness, crack and break. Replacements are easily sourced online.
From seeing recent posts on social media from MRTs and others making the most of the recent snow in the UK I'd strongly recommend using snowshoes. The major advantages are
a) not post-holing and getting wet feet/legs, or unexpectedly post-holing into a twisted ankle situation when you plunge through powder only to hit uneven ground and roll your ankle, or get it trapped between boulders. I've happily walked on top of snow that others have post-holed up to their groins every step!
b) not slowing down. I'm doing virtually the same pace with snowshoes as I get on similar terrain in summer.
If you have to carry them up a climbing route they may be more hassle than they're worth, but for winter walking it's a no-brainer.
