I'm an authorize brooks dealer... in my opinion the spring do not add comfort to the saddle but comfort to the ride... absorbing the bumps in the road as you ride.
Brooks saddle take time and effort to break in... get some proof hide and work it into the saddle ever day for a month or so and ride as much as possible.
The saddle needs to be broken in... also make sure you have the saddle adjusted correctly... try different angles and rail positions till you find one that is tolerable enough to ride. Give the brooks saddle a chance...
If you want to stick with brooks you could try the aged flyer or aged b67... the aged saddle break in little quicker. You may also want to look at the b17 imperial which has a cutout to relieve renal pressure... also breaks in a bit quicker.
Other wise... just get a cheap mountain bike saddle
