I've used fixed 4 and 6 power scopes. I also have used variables from 1.5 x 6 all the way to the much hated 4.5 x 14.

Fact is EVERYTHING can and will work.

I hunt with a variable 99% of the time these days. To me fixed power scopes dont offer any advantage. When I hunt in thick country I like the option of turning my scope down. If I have a longer shot I like the option of being able to turn it up.

Obviously a 4 or 6 power scope can be used for close shots, and it can be used for long shots as well. However with the modern variables being very rugged why not have the best of both worlds? For me thats a variable.
