Not sure which one you have but the one I ordered is the one with less padding, marked 30, there is also a 40. I guess it will also come down to the actual shape and width of the saddle. As I’m a big dude I opted out for the narrow saddles line (big thighs and such, trying to avoid rubbing) 
Interesting approach, if my LBS will have it I’ll try to check it out.
If you didn’t notice any rubbing prior to those big days then maybe its down to the way you sit on the saddle now? Not sure, not a bike fitter But it is strange that it used to be good but now it is not, and nothing (I am assuming) changed in terms of your bike geometry etc.
That’s the one I ordered, we’ll see how it goes 
Have you maybe tried the more padded 3.1 version by any chance for comparison?
