Just for the heck of it Pluto, let me ask you this.....do you feel that 80% letoff helps you in any way while bowhunting?
Big Country, no not really. I have only been archery hunting for about 10yrs. The bow I was using was a Fred Bear Whitetail that due to it' s design could never be tuned properly. It was a 50% bought from Wal Mart. I was only accurate to about 20yrds. The first of this month I bought a new bow. I am shooting this one as good at 40yrds as I was the old one at 20. It is not because of the 80% letoff, it is because it is a better bow.
I don' t think the 65% rule will ever effect me. First I don' t measure a trophy by the size of its horns. Some of the most memorable deer I have ever shot were doe. To me the memory is the trophy. The skull just reminds me of it. Second, I don' t hunt in areas that have many BIG BUCKS. I hunt the lower TX Hill Country. The deer are small and preportioned but not going to put fear in a South TX monster.
