+1 for the jett. I actually think the cutout does extend forward enough. Funnily enough, really padded shorts don't help as they just take up space in the cutout. Also I tilt my saddle up (by about 9 degrees - according to my iphone). I find it feels like a nice comfy cradle on my sensitive front parts. The other thing to check is your reach on the bike. If the bike is too long/is set up too long, then you will be too stretched out which will rock you forwards & put even more pressure just where you don't want it!!

If you go to a Specialized concept store they do test saddles so you can try the Jett out. They will also measure your sit bones. I am 5'1" & take the 155mm on my road bike, but the 143mm on my track bike, as I am rocked further forwards & often on the drops - so the width you need does depend upon your position.

Good luck
