I have/had Meopta, S&B, Leupold, Vortex, Redfield, Bushnell, Nightforce, Trijicon, Zeiss, etc.... 1" tubes, 30mm tubes...1-4, 2-7, 3-9, 4-12, 1.5-6, objective lenses from 28 to 56mm, yadda yadda yadda. Of all these I find the smaller, 1" tube Leupolds the lightest. So if you want light weight, stick to 33-36 objective on 1" tube - 2-7x33, 2.5-8x36, 3-9x33 Ultralight, etc. If you want brighter glass, you will pay more in weight and cost. 50mm objective on a hunting scope (unless I'm hunting from a stand at very low light or at night) I find a bit too bulky and my aging eyes can't tell the difference between it and 2.5-8x42 setup. They can tell difference between 28mm Leupold lens and 42mm Meopta/S&B lens at dusk though even at 4 vs. 8 magnification respectively.
