Deciphering Airone models

[benb]

I’m looking for a new Airone.

I have an Arione VS that I think isn’t working anymore. It has no cracks or anything but I think it’s sagging when I’m riding and I’m having weird issues with my left hamstring/glute/sitbone that really seem to be bike specific. It makes me think the saddles pinching something. The saddle looks brand new but it’s in about it’s 4th season. This issue has been a major drag this year.

The Arione used to be just one saddle. Now they have tons of models and two sizes in some models. I know I want the 126mm or the classic 132mm.

Is there any way to tell which ones have stiffer padding and/or shells? I’d probably prefer to be on the stiffer side, though I know the classic design and the VS work for very long rides for me when they new and functional.
