Sounds like a bargain if they work that well, I will look into them.
But to be clear, you do 60+ miles comfortably on the road bike? Hybrids are wider tires so I would like to know about comfortable road bike distances. ;-)
I wish I had the time to do that sort of mileage in one go.
50 km (or 31 miles in old money) is about where I max out at due to time constraints. Yeah, I'm slow too...
Before I got the hybrid back in March, my road bike was my do-it-all bike, so yeah, I've ridden the above sort of distance (commute to and from train stations plus a bunch of urban riding in between) wearing ordinary hiking trousers - and no sore bottom.
The OEM saddle supplied with the road bike was ghastly. Too narrow plus wrong shape equaled painful and then numb lady bits after only a couple of miles. I bought the Charge pretty soon after getting the bike going by what I saw people saying on here, and found that it worked for me.
The Ladle is the ladies' specific and is the widest. The Spoon is the middle width and the Knife is the narrowest. Charge also do a posh version under the "Fabric" name. Price does vary - at the moment they're selling between £18 to £26 depending on the colour.
This is the one I have (although not in that colour):
