The flyer imperial wasn't used so much, maybe 2 years old, and 1500km. The sit area has somewhat formed comfortably, but the increased sagging with age has caused discomfort on the nose and bridge. A new one sags about 5mm. My used one is around 8-10mm. when not sitting on it. I did try sitting on a brand new one since I've forgotten how it felt like when new, and the 4-5mm difference in less sag greatly relieved some of the genital pressure. But then the sit area was hard and uncomfortable without being broken in.

I wish some company would make a low step bridge/nose bridge like the SQ Lab, but with a rear design of a brooks.

I've tried more than 15 saddles but haven't found a supremely comfortable solution. I have 13cm sit bones, and any saddle that is physically less than 15cm wide will be very uncomfortable. 13 to 14cm is impossible for me. 15.5-17cm would be better, depending on the side curvature. Sit area needs to be tilted -1 to 0 degrees down. Anything lower and I'll slip forward. Anything with a beak nose (SMP), hammock shape (brooks), deep falloff curves towards the sides, causes pain on the perineum. A bridge/nose lower than the sit area is preferred. A flat sit area with sharp leading edge causes pain for me on the flesh in front of the sit bones on the downstroke. So a more rounded edge is preferred. Moderate saddle softness is preferred, but extreme softness causes sinking and then pressure to the flesh in front of the sit bones on the downstroke. I also prefer a slightly upturned back end to push forward against.

I was thinking of testing a Scoop saddle, but the flat and shallow versions are maximum 142mm, which is too narrow for me. The 155mm models only comes in radius version, which has a kind of hammock shape, so I'm not sure if it would work for me.
