I've taken mine out in the Belgium Ardennes (which is kind of hilly compared to Holland) and participated in a 60 Km tour with my Enduro S-works. At that time, the bike was setup ultra light with short 125mm forks and light wheels, so it climbed great. Apart from when it got really steep (like where you climb 30m every 100m travelled), the rear starts to sag about 1cm on the shock and rebounds each revolution of the cranks. This gives great traction but takes getting used to. I was running 60 psi in the SPV chamber, so maybe with more pressure, the bobbing might be minimised, will try that on my next ride in Belgium, but now I have the Fox 36 fork installed with heavy duty wheels, so climbing will suffer a bit.
