SDG Grand Prix for a while, no longer available but well padded, mid width and still doing service on the folder. Flirted with Bel Airs but they were not wide enough for my backside and I had to accept they were not for me and put them on ebay. Finally realised I had wide spaced sitbones and went hunting wide saddles.
Henge gets rave reviews but all seem to be for previous model with more padding. I found current model, although wide enough, was not comfortable if used for more than an hour. Ergon saddle had a sweet spot. If you were on it (25% of any journey) it was really comfortable, if you were off it (75%, of any journey) it was excruciating. 2 more happy buyers on ebay though.
Wide WTB Rocket V seems the best for me. Shaped like a wider Bel Air and available at a range of prices depending on model. Honourable mention for Terry Figura Max Gel which is to racing saddles what an armchair is to a wooden stool and does sterling service on the 29+. Needed to play to get it angled right and front is wide enough to remind you that it is there.
