If you have Pro Falcon 132, it will be quite similar - the shape intransverse plain is very similar, Ryet is shorter and has slight rise in the back for additional support if you need it. I've had Spec Power before and I think the Mirror is very distant in terms of shape from Falcon or Ryet. I did not like how steep the transition from wings to nose is - it leaves very little efficient space to sit on.
Mine’s 142mm, so also not far off the Mirror in terms of width. I agree with you on the wings, my bike fitter wasn’t a fan of the Mirror either. I’ll give this one a try and compare. What throws me is that I’m running the same setup I’ve had for years without issues, so it’s odd that problems are showing up now. Might be the new shoes and the position of the cleats relative to old shoes.
Appreciate you sharing your thoughts on the saddles.
Edit: I’ve ordered a saddle! Will share more info once it arrives and tested.
