I can't add anything different, except that I cannot overestimate how important the tilt of the saddle is, even in increments of 1 cm. I need mine to be slightly tilted up.
I switched from a Terry Falcon to an Oura about 4 years ago. I was very suspicious, but when I was being fitted for a new bike, the shop owner recommended the Oura, as I had dealt with constant pain in the soft tissue and burning, since I started riding, despite having a cutout. Although my sit bones hurt for a couple of weeks in the transition to the Oura, I learned how to use my core strength to sit back and the pressure was totally alleviated. I now have an Oura on all 3 of my bikes, including a hybrid, where I am upright. But, as Murienn said, if it was too wide for me, it would be really horrible.
