Ana,
I would guess that as long as your sit-bones are on the padded parts and not on the hard edges, it would be a good size. Saddles are made for a range of sizes, hence the generous padded areas. The next larger size may be too big and interfere with pedaling motion. But as we all know, there is more to comfort than fit. I could not get the Jett saddle comfortable no matter what I did. I raised the nose, lowered the nose, double checked the fore-aft and seat height; I ended up frustrated with it and ditched it for an Aspide Glamor. Sometimes the extra padding is just not comfortable. I think it was just not supporting me properly. The Aspide Glamor has no cutout and is thinly padded and you would think it would be painful looking at it. But for me, it was fine, but a little flexy so I kept looking
I have since bought a Bontrager saddle (they have a 90 day unconditional return so I thought 'what the heck'). They have several models, and I went with the RXL, which again has no cutout, thin padding, and has firm support (carbon shell). It does not look as comfortable as the Jet, but it is night and day for me- When I die, I am going to be buried with that saddle!
Tzvia- rollin' slow...
