Yes go wide -er and metal on Stirling. Long skinny edgeless on trails when crusty is horrifying.
Dare I say it - the upper Mtn is tailor made for big 75mm boots with buckles and a stout cable binding - not just 3 pins. If you fluke some soft snow in the lee of the summit you'll have much more fun too.
Fwiw: I May even try the NTNs up top - only if there's some worthwhile fresh or slush?
Also worth considering Mr T is some kicker skins for your Wider BC skis. They make a big difference on firm, although skeet ice & pie crust will test the best skins. The BD kickers come in a 50 mm waist but I'm sure you could trim if that's too wide.
When waxed up with Globstopper, Kickers provide OK glide if you're not overly worried about speed on undulating terrain and can act too slow your descent too - handy - as long as your edges are not covered!
...something to ponder for another time?.
Thanks for the report by the way - I look forward to my run there in ~ 3 weeks, with my wide, heavy gear.
A tricky season for the smaller resorts and Buller. Too many near misses with rain this season unlike 2018. ( l:-(
I was carrying my BD kicker skins in my goretex jacket pocket today. I was tempted to put them on. I should have taken the wider heavier Madshus Epoch skis and fitted my kicker skins. I went out on my metal edged Fischer Nordic Cruiser skis. They were too fast on the ice.
Slowing my descent , climbing better. Yes, I needed that today .
Now I understand , Master. I will be a better prepared grasshopper on planks next time .I will look at acquiring the Globbstopper for the kicker skins. Doug at EMC will know about that .
