Deliberated for some time before buying my 160. Never regretted the decision. Its the most foregiving bike,solid, whatever you throw at it. I have a spesh stumpy and 224 evo, but I still always go for the 160 as it will do anything from XC to DH.
I was always fed up of breaking the lighter bikes, this one just never breaks. As long as its serviced regularly.
Mines now up for sale! Its only taken me a year to decide that. I need to reduce my 'garage' and do more DH and Road now. I would seriously consider a Five with a Fox 36, unless you do more big stuff. Only because you can save maybe 3-4lbs.... or just miss a meal. (its very costly trying to reduce weight through ridiculous pricey bling.. IMHO
