I agree and disagree with the original statement... I do believe that too much of a good thing can be bad.
However, I am greatful for some of the advancements made in the way we hunt today.
For instance, I like having a compound bow over a recurve..I would not have taken as many deer as I have over the years, had I not used a compound bow.
But in the same respect.... the bows get better and faster every year. Where does it end?
Scents is another area...where had i not used it, I would not have taken deer I did on certain occations.
And lets not forget the grunt calls who haven't been around all that long..
I guess you have to decide for yourself what works and what are gimmicks... And the only way you find out is to try it for yourselves...
