All I can say is that I won't buy another single pivot bike.
My orange was a 2009 so it was pre boost valve bear in mind.
The orange felt over-damped and a bit wooded in comparison. The dw felt great, rolled over sqaure edges perfectly (compared to my blur LTc which has VPP2) and felt very plush – it also climbed great (I never used pro pedal)
I rode with marco (ciclo Montana) in sierra Nevada and the decents are longer/more sustained/gnarly than in the UK and the climbs are bigger/steeper/longer than here and he said the 5spot was the perfect bike (his weighed 30lbs)
I was inclined to agree as he was ace.
One positive with the orange is that it only has 2 bearings and they are a piece of pi$$ to replace.
EDIT- I also believe that the 5spots have a slightly revised DW design which is better than the 5year old version on the mojo.
