The SMP Stratos was the answer for me. SMP makes many saddle models with a full length center cut out. Start with the right width and don't bother with any of the models that have minimal padding. SMP suggests saddle width based on waist size, but that means a waist size without extra weight. Think back to your youth for that. I use a narrow width.
