I'd go for a Toupe or Toupe Gel. I've had an SLR too and it was okay, but the Toupe (in 143mm) is just more comfortable over longer distances for me than the SLR was.
Do NOT get a Concor. Awful. I made it 5 miles on it before I had to turn around and go back home and take it off. Most uncomfortable saddle I've ever had the displeasure of using.
