I'd definitely go with the 100 yard. Maybe even 75. The very few times you have to shoot further, you can compensate. But why sight higher if 95% of your shots are closer. I'd rather be dead on those 95% of the time shots rather than what to worry about of you are not.
Even my elk hunting rifles are sighted in for dead on at 100 yards as thru the years, most shots have been under 100 yards
