Question on draw length for bow:
Dalegribble,
Let me tell you that draw length is probably the most important factor in setting up and shooting (or) hunting with a bow, period!.
I have been hunting with a bow for many years and over those years, I have found out, that no matter the mfg of archery gear (proper draw length for each individual is paramount to accurate shooting).
A 31" draw length is pretty long for most folks. I am 6'1" and thats what they started me out with years ago. As time went on, I found out that every time I shortened the draw length (I was more accurate) until I finally setteled on a 28.5" draw length. Most competitive archery competitors usually shoot a little shorter draw length. Of course, when you shorten draw length, you decrease your arrow speed. You can up the poundage on your bow to compensate for lost arrow speed.
Bottom line is see your local proshop as others have suggested. The new compound bows, like Mathews, Bowtech, Bear, PSE, etc., all have great top of the line archery equipment.
I now shoot a Mathews Drenalin bow at only 63 lbs and a 28.5" draw. I get good pass through shots when hunting, (even a hog I recently shot).
Don't settle on a cheap price system if you can help it. Get a quality bow set up and have your pro shop set it up for you. They will make sure you get the proper length, which is the most important factor in my humble opinion. Good luck. Rick
