I know you already purchased a scope but, for future reference for some, there is some drawback to higher front objective. The bigger the objective, the more light that it will draw in. Unfortunately, it comes at a cost which is usually your power or your zoom.
Next time you are sitting at the house in low light, take a rifle with a smaller front objective (say 30mm) and put it next to one with a higher front objective (40 or 50mm). Zoom both of them in on max power. What usually happens with the bigger objective is that they start to wash out at higher power. So, if you ave a 3-10 scope with a 40mm, they usually start to bright wash at about 5 power whereas a 2-8 with a 30mm objective will probably let you zoon all the way to 8 power without washing out. Just something to think about when purchasing a scope for certain conditions. There is some give and take associated with it.
I own leupold, Nikon, Bushnell (the older models) and a few other very high end scopes. The best I have found for low light conditions is actually the Burris scopes. The only drawback is that their field of vision is small so you usually have to start on 4 power and zoom up once you are on the animal.
