In the end (snicker') you are the one that will know what feels best. I just got my rear sized and was surprised it that the recommended saddle width was between 143 and 155. I would have bet I was like 170 +++ So the sizing at least showed me a starting spot to look, that has likely saved me some time and trouble. For me its now a try until I find the right one situation.
Best of luck in your search for comfort.
