I've read the thread on angled vs straight, but here's another. Should I go with a standard 20-60 power eyepiece or would i benefit from a 25-50 wide angle? and because I do some backcountry hunting and alot of open country is it worth getting an 80mm instead of the 65mm since its only 8oz. heavier or is the 65mm enough to see most things in all situations, since I only have the money to own one scope !
