I managed to buy a second hand, unused Brooks Cambium C13 Carved from eBay. For me, the hammock design seems to distribute the area of support better than the SMP saddle I was using previously, so I don't get the point loads on my sit bones, but crucially don't get numbness from pressure further forward, either. I tested it out successfully on a 600 and got round without any problems. Definitely the best of the various saddles I have tried recently (for my particular situation). I have not put so many testing miles into the Tioga Spyder, but I think it does spread the load in a similar way, although it is a bit stiffer and the hammock effect is not as pronounced as the Brooks.
Another thing I tried on the 600 was applying Hydrocolloid plasters before the event (I have previously used them as first aid for saddle sores on long distance, multi day riding). I can't definitively say that they were effective as a preventative measure, but they certainly didn't make things worse.
I'm happy with the Cambium, so I'm not investigating the Infinity any further for now, but interested to hear what experience other people have with the saddle.
