It's a pity Khales have stopped the 2-7x36, and I have a feeling Swarovski are stopping the z3 in 3-9x36. I have an older Nova on my rigby in 3-9x36 and love it - to be honest its all the scope any body needs for 95% of hunting. With QD mount the other 5% can be accomplished with open sights. I also have habicht 4-12x50 in a 1' tube - its getting on the bulky side and to be honest I don't think in the dark under the moon or last light I can see any better with it than the 3-9x36 - perhaps I can use a little more magnification.
