I'd certainly suppport the opinion of jason22, as the Scarpa Rangers are a great boot for waterproofness (Gore-Tex liner), with leather that's easily looked after - although they are reasonably lightweight, I'd have to add that they're designed for valley walking and rambling. It really depends again on what you're going to put them through.
Going to the other end of the spectrum, you could say that the Scarpa SL's would suit a more challenging style of hiking, but would increase in weight by 400g or so to 1600g.
If you don't mind moving away from leather walking boots, you could gain a great deal of weight back. Something like the Berghaus Torc LX - lightweight (800g ish), Gore-Tex and a good foot hold.
