Weight makes a huge difference! specially if this is your one all be all bike that will clear a jump a 10 stair or a 10 mile commute through the urban country,peddaling a beast will take the fun out of riding in the long run since there's no ski lift in my back yard for just Dh only so i still halftoo peddle up grades or ramps and the uphill climb when you live i a hilly area. remember its a one all be all no no money for a second bike here.
