I've ridden an Avocet O2 for years (not the same one, but several of the same on all of my bikes) They do not make them anymore so I purchased a Terry Zero X saddle and I really like it. I use it on my mountain bike. It is minimally padded, but enough for me.

You can purchase them on the Terry Precision Bicycle website.

They have a nice return policy on saddles if you do not like it. Check it out.
