There are those who prefer high magnification capability of their optics, and there are those that prefer low magnification, there are those who will want the 'biggest' objective they can get by with atop their stick, yet others wont go above a 40mm objective, some folks will even prefer smaller objective diameters.
Also, the 'larger' diameter optics stand off the receiver more, that is, the overall mounted height of the scope will be higher than if you chose a smaller diameter objective unit, the higher the scope is mounted above the receiver, the closer you get to having to install an a elevated cheek piece of some kind on your buttstock.
The question is... what do you want, or what do you expect to accomplish with 'your' optic?
Others will chose optics based on overall length and or the weight of the scope.
Then you have the 'features' offerd on the various optics....
Based on your question, and not knowing exactly 'what' your perimeters are, I would say that the Leupold VXIII 3.5-10X40 is the perfect optic for your application.
It is not 'too' large at the objective end but will offer adequate low light usability, and the magnification range is low enough at the lower end, and high enough at the upper end of the scale to allow you plenty of latitude for both close in shots and the longer shots you may take, also 10 power is good enough to allow for 'antler inspection' at range, well, at moderate range anyway.
As for the weight of the unit you inquire, it is not an excessively heavy scope, matter of fact, it is in the lighter weight neighborhood of scopes.
I think you have made an excellent choice, remember, don't skimp on the bases and rings, a good scope setting in 'cheaply made' mounts is a heartache waiting to happen. lol
