I don't think that Brooks saddles are for everyone. Especially for rides over 2 hours, I prefer saddles that are wide in the back, have a flexible saddle-frame where each side moves with the motion of my pedal strokes (usually come with a center cut-out, but the movement/flex is more important than the slot), and that have a VERY narrow nose. These days, I also much prefer hard saddles over super-cushy ones. Gel saddles are downright uncomfortable for me too.
I currently prefer the Specialized saddles that use the width of your seat-bones (I ride the Alias 155, the widest that they make), and the saddles on my older bikes also tend to have the same basic geometry described above (Terry Fly and the non-gel Terry Liborator).
If the Brooks does not work for you, then I say keep trying new ones until you get one that works. Saddle choice can make all of the difference in the world on your rides.
Have fun out there!
