Correct me if i am wrong but isnt that bow somewhere in the 30" class. And to answer youre question yes I beleive it is better to shoot the bow at the highest poundage as it will alow for easier tuneing (my opinion) The bow will be closer to spec right off the bat. I used to think that you had to shoot 70lbs all the time, but a broken back convinced me that 60-64 is more than o.k. for 3-d, turkey, deer, spots, just about anything you can put in front of me. Plus at the end of the day wy shoulders are still working like they were at the start of the day.
I cut things up and split them down!
