I ride the Ldy Gel Flow saddle as well and can offer a couple of observations:

It's a wider saddle - has the same shape and width as the Terry Butterfly; in fact, I've read/heard that it's the same saddle frame. So it's probably somewhat unlikely that it's too narrow for the OP.

Even thought it has "gel" in the name, it is not (to me, at least) a squishy, overly padded saddle. In fact, it took my sits a few rides to get toughened up for it. Now that I'm used to it, I find it extremely comfy. For me.

It's possible that it may break down over time as many saddles do eventually, and perhaps that is what is going on here. I haven't ridden enough miles on mine (maybe 1500 total over the past 3 years) for that to happen.

No tailbone pain here, but I ride in the drops and bent over quite a bit and am fine doing that on this saddle. That probably keeps my tailbone and ligaments well out of the danger zone.

Good luck, deskrider!
