I've done 4 ski trips to Naiset, most recently though in 2003. Looking at revisiting this March which is the best time for snow conditions IMO. Not much has changed I would guess other than Assiniboine Lodge now handling the Naiset bookings, and the new common area/cooking shelter. I assume that you have done your research and know all that...
A few thoughts-
-Start out early from Shark. It is a fair distance and while the trail as far as Bryant Creek is well travelled, it may not be over Assiniboine Pass. Once over the pass, the trail can be tricky to follow in spots if not broken. Best not to be doing that in the dark. Same goes for skiing out, it is pretty flat for most of the way so will take most of the day despite being "downhill".
-I would allow more than one day touring up there if you can, to make the ski in/out worthwhile. We have always spent 4-5 nights. For longer trips, paying to have some of your supplies flown in is an option, as is flying in/skiing out which is what we did in 2003.
-Maybe things have changed now with the cookshelter, but bring collapsible water bags and be prepared to locate and clear out the waterhole.
-What ski gear to bring? Much of the terrain is fairly mellow and rolling and while there are many good places to make turns, many go there just for the touring amidst spectacular scenery. It's a compromise between touring efficiency and downhill performance. On all my trips there I used light T3 tele boots and old school 85-65-75 tele skis, which struck a good balance for me. One of the "backcountry system" boots along with light metal edge touring skis would be the ticket for going in and out, but not ideal once up there. OTOH modern fat powder boards and AT boots would begin to seem like anchors on the 25 km of trail.
Your call.
-Best resource for tours would be Chic Scots "Ski Trails of the Canadian Rockies", which has many of the standard tours. There are many other tours too, but best to start with the trade routes.
-I would recommend the Jones Bench circuit with a stop by the Nublet for some turns.
-A variation on this in STABLE conditions is to go through "Jones Notch" and return via Jones Bench.
-Wonder Pass and beyond to viewpoint is a nice short tour with some easy turning opportunities.
-Ellies Dome is probably my favorite, great viewpoint and turns, but can suffer from exposure to wind, as does nearby Mt. Cautley.
Lodge staff were always friendly and helpful, but remember that they have their clients to look after. Be completely self sufficient! Other than firelogs for your cabin which you will need to buy from them. Bring cash! (it is BC afterall) :)
Hope that helps. Have a great trip!
