Of course, not all saddles of proper width may work for you. I switched a month ago from a basic modern shell and padding saddle (Volt) to a tensioned rubber saddle (Cambium C15), and it’s like the saddle disappeared. Which is a good thing. Hopefully you will find one that isn’t a problem.
I should say that most people who try a tensioned leather saddle and a tensioned rubber saddle pick the leather saddle. Also, tensioned saddles tend to be heavy and probably a bit of a liability in a triathlon.

As well as sit bone width there is width at the middle of the saddle which can affect abrasion and pressure on the inner thigh and groins, the taper of the saddle from nose to to the widest point (narrower at teh midpoint is better), which can cause pressure on the inner thigh as your leg goes down, and whether the contour of the top across the back of the saddle is flat (not higher in the middle) or arched (higher in the middle). This is just a matter of your shape and preferences. I found I like cutouts and I formerly thought I needed them, but I no longer feel that way. I use vintage Ideale leather saddles. I used to use Selle AnAtomica, and before that Specialized Toupe and Alias.
