First thing I'd do would be to make sure I took some proper snow-pegs for the tent! 18-24" hollow ally tubes would do the trick. Because I was pitching on deep snow - even if the surface was trampled down a fair bit - the pegs (including 4 ex-army 9" ones) were not initially providing much grip, necessitating a much "sloppier" pitch and plenty of snow on the bottom of the tent. Once they froze in, the tent itself was pretty solid, but the interior space was probably reduced by about 30-40%. On reflection I could have cut some longish branches and used those as pegs, but at the time the priority was to get the tent up!
I'd also make sure I packed in plenty of time, but circumstances dictated otherwise in this instance. One piece of kit I really missed was forgetting my little Etowah 11 meths stove (which was still on the sofa when I returned home!) With a little meths (and it had a full 4 oz bottle in its bag), this would have provided plenty of brews on the trek in, yet takes up very little space. It doesn't rely on wood, which was a problem for the two camping wood stoves I carried (the Vital and Emberlit Ti.)
Boots - make sure they are the right size! Having said that, I'm still happy with the packboots performance overall as described above (fairly lucky really, as it was the only pair of boots I took!) I will buy another pair a bit smaller though, for my next trip! (So anyone with size 11+ feet looking for a pair of super boots, let me know
I'd also make sure I put up my new tent - and more importantly burnt in the portable stove and pipe - before embarking on any trip. The tent wasn't a problem bar the pegs as it was similar to my previous Kifaru and Seekoutside ones, but the 10ft titanium stovepipe is an absolute bitch to roll the first time, particularly on thick uneven snow! And the edges are like razors, so plenty of rude words used before eventually getting it rolled.
I over-packed, basically. I took way too much gear (did I really need 3 knives, an axe, 24inch collapsible bowsaw (with spare blade) and Bahco laplander folding saw, for example!) ditto 4 sets of thermal baselayers, 6 pairs of thick sox, three sets of stoves (Trangia 25 set plus 4.5 litre trangia pot, Emberlit Ti, Vital stove) plus the tent woodburner. Foodwise, I also went way over the top, and had enough for a month, let alone a week! This included a kilo of flour, baking powder, yeast etc with which II intended to make bread, but the soaking wood tended to put paid to that. I also left behind a kg of rice, half kg of spaghetti, various packet meals, dehydrated peas, onions etc. I should have packed some cuppasoup type stuff. Stuff I took on a whim but found very welcome was some full-fat powdered milk (can't stand the skim-milk stuff), two tins of condensed milk and a squeezy bottle of golden syrup. Nothing like a big cup of tea or coffee first thing in the morning, with lashings of condensed milk or golden syrup! (Yes, I know this sounds vile, but even though I normally don't sweeten tea or coffee, your body craves easy calories/carbs in low temps, and this was a very good way of getting them in!) Also both go well with porridge too. Together, an ideal breakfast when the thermometer drops.
The Ribz I found to be very useful, both on the trips to and from Oslo, and whilst there. They hold a remarkable amount of kit (for example, mine held 2 phones, an Android tablet, a Palm, one of two battery packs I took along, passport, wallet, gloves, spare spectacles, car keys, loose change, trip itinerary, satellite photos of the area, two packets of cigs, cig lighter, and still has space for a lot more.) On the trek in they seemed to counter-balance the smallish rucksack I wore (circa 35-40 litres at a guess) and didn't get in the way of anything. Got a few stange looks at the airport as they are camo-pattern, but were never queried or regarded as carry-on luggage.
