I got my Model-T in the summer of 09. I planned to use it for 3-D and targets. It was 40# @28", 64" with carbon/foam core. It was a lot lighter weight than I usually shoot and the 64" length was also longer than I had shot for quite awhile.
The bow was a pleasure to shoot with light carbon arrows and it turned out to be very flat shooting. When hunting season rolled around I found myself without a shorter, heavier bow so I decided to hunt with the longer lighter weight bow. I found that it even shot arrows with 200-250gr up front very well at 20-25yd and I was confident it would do a good job on any whitetail.
In most cases the 64" bow worked out just fine. There was only one time when I lost a chance for a shot from my ladder stand because of the bows length. Had I had my 54 or 56" bow I'm sure things would have been different.
This past season I was back hunting with a 56" Classic Hunter with carbon/foam limb core. That bow is every bit as smooth and accurate as the longer bow in hunting situations while being more maneuverable and quicker to bring into action. I have found what works best for me and I won't be changing any time soon....
