How should I set up my rear shock (with ProPedal) to minimise bob when climbing? I've got a Fox RP23 rear shock which I'm very happy with, apart from the apparent ineffectiveness of the ProPedal setting.  Bob is very noticeable on climbs in both positions.  It's hard to say which is better.  I don't expect to eliminate it completely, I just want to know that I've got the optimal setup for my bike and riding style. The manual is pretty vague so I'm wondering if anyone has any useful tips?
Pro-Pedal provides bob resistance when on, 1 being lowest.  

Try this.  Pull out the numbered knob and position it so that "3" is in line with lever.  That will give you the most Pro-Pedal.  Now, try riding up a hill with it off and again with it on.  You should notice markedly less bob with it on.  If not, I might take it to a shop to make sure that it is working.
