I currently have a 25 inch draw length, and am pulling 60# with a 354 grain arrow getting 250 fps. I shot 2 deer last year and got 2 pass through's with 75 grain muzzy 3 blade. However i did not hit any bone except a couple ribs. I was just wondering if i should crank my bow up to 70 pounds next year for the speed, or if i should leave it where it is comfortable and easy to pull.
