Hi Serenity: you’re asking questions that my cohort (mid 50s) are asking too.You're abit younger than me, I'm in my early 60's. I've tried different combinations over the years with varying success. As you say, Gwinear ungroomed is better with wider skis and plastic boots but you have to accept the extra weight. Never tried NNNBC, only the traditional 3 pin 75mm. Much difference?
COvid has changed things - 2 years of no winter - almost a 3 year gap for most People, has lead to a loss of fitness and muscle mass.
A case in point, I have some SOFTSHELL Gen-purp mtn pants that used to be quite tight across the thigh. Now they’re fairly comfy - which is good but to me, a sign of lost muscle, which will happen through 50s & 60s even if your exercising regularly.
Do some research on the latest gear. Work out where you most plan to ski and decide, what gear is most appropriate.
Be prepared to pause/retire/sell stuff that doesn’t fit you body or ski style/destination anymore.
If you’re happy to spend Money to upgrade your kit, along with getting fitter/stronger, you’ll have a better ski experience.
Can I ask what gear you are mainly using?
I note, Gwinear can be quite rich, rutted and treacherous. It’s often not an easy mtn to ski. It was my first day trip with the uni - what a wake up!
You need metal edges, a bit of ski-width, stout binder (ideally inc a cable) and something like an Excursion or T3/4 (boot) to get the most out of MSG, most of the time.
There can be ideal days, (fresh dryish snow), when you may almost be able to ski on the narrowest, edge less toothpicks (sub 50mm waist), and floppy-floppy low-cut leather boots, and non-cable binders, but those days are pretty rare in my experience. To be savioured and well photographed!
Please feel free to share?
You aren’t alone! (;-)
