The Leupold 3.5-10x40 and the Swarovski Z3 3-10x42 are also awesome lightweight options, optically I would give the nod to the Z3 but both are excellent lightweight options.
One thing to watch on the Z3 is the BRX reticle option, if you like that style of reticle its very faint and I lose it at low light, get the BRH (Heavy) if you go for this reticle style.
Sold My Z3 's Very Clear and Bright - also Light - but i do not like the FAINTNESS of the reticles either - Eyes are too Poor ! RJ
