The question is what are you shooting and how far.
I can't argue with kraigwy's advice and I've even repeated it based on his experience alone.
However, I use scopes up to 40x for shooting woodchucks and I strongly prefer high powers BUT the distances I shoot, maybe 350, 400 yards, the issues that creep up at 800 or 1000 yards are just not significant.
I even use 25, 30, even 40x at 100 yards. Don't need it but I like it and I'll never be shooting far enough to see the negative effects.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
