Knot - I have a 155 width on my road bike and love it. It's the exact same seat without the cutout. I find that the edge leading into most cutouts feels a bit sharp on my bit area so mine just has a groove and a more gradual transition. When I went to that seat last year, my riding changed. (along with getting the 0 setback seatpost for my short femurs). I got mine at Performance on sale. If you remember, I also went with tri shorts pretty much exclusively at the same time. Even more comfy for me then since I get more airflow even without the cutout. When I jumped on my bike for the first time this year (last weekend), there was no learning curve for my sit bones or bits this time. The "wings" of the saddle give a bit for comfort but are stiff enough for support. Hope this helps.
