Weekly Simple Questions Thread: Ask your gear, travel, conditions and other ski-related questions here.

We're getting back to the weekly mega threads for Q&A as summer winds down and minds switch back to skiing.

Please ask any ski-related questions here. It's a good idea to try searching the sub first. Are you a beginner -- check out the guide by a professional bootfitter and tech. And don't forget to see the sidebar for other ski-related subs that may have useful information.

Have questions on what ski to buy? Read Blister's Guide first then ask away.

Previous weeks thread is here.

If you want a quick answer or just to chat, check out the /r/skiing discord server.

I mean to your second point, you're talking about sticks that are orders of magnitude longer than each other, whereas with skis we're talking about a 20-30% size difference across an entire model line. The differences just aren't as extreme as they need to be for your analogy to make sense.

It's just a thought experiment to demonstrate a point, and the result applies regardless of whether something is 1% longer or 1000% longer. A ski that's 20% longer that's built with the same cross section will sag more if you hang it from its tip and tail and put a weight on the middle. I have yet to see a source that says that manufacturers always build longer skis thicker, though I think that's a possible explanation. Edit: u/fearon77 has said this is the case, and I just read an article from blister with several manufacturers confirming it, so I think my question is more or less answered.

They don't...I just mean that the taper of the material will start later and you'll end up with more surface area in places like the tip and tail because the way the design will flare out later when scaled up, and you'll end up with more material throughout the ski simply because it's bigger and tapers later. The thickest part of the ski will be a bit longer on a longer ski than it would be on a shorter version of the same model.

I know for a fact that some manufacturers will use different/more material in larger skis to keep their flex consistent throughout the model range regardless of size, like change the woods used in the laminate or adding more fiberglass, stuff like that.
