I waited about
6 months after surgery before I got back in the saddle. I did schedule surgery in November so that helped
Ask what your doctor recommends as far as timing. Before surgery I started looking at the same seat you did the Hobson and I also looked at recumbent cycles, much more comfortable seats. I have a Brooks Champion Flier, basically a hard leather seat with some springs. I wear padded shorts for rides over 10 miles and I have had no pain in that area. I wish you luck in your search for a comfortable seat, you don't want to have to give up biking.
