Buzz, maybe maybe not but thx. I suspect your right 100mm is likely better for most as a Western daily driver but like anything that leaves other gaps to be filled. Bigger for powder and narrow for frontside, or between storm skiing. If I went with a three ski quiver I'd probably go something like 78 - 98 - 118+, others might add or subtract a few mm based on weight, size and preference.
110 or so seems to be a sweet spot for a few guys around my size in that it is a really good if not ideal powder skiing and good soft conditions daily driver without giving up much at either end. 100mm for me not so much, as it gives up too much in deeper snow. 120 ish not nimble enough in marginal conditions.
Tip rocker (and tail) has made many a ski quicker and more manageable in a bigger widths and lengths. Case and point the first gen MX108 would not have been on my daily driver list.
Yeah, that is how I see it too. Good quiver call; high 70's for hard snow, something in the middle for variable conditions (ski flex and characteristics are more important here than width), and a wider ski for soft snow.
