I am shooting an LX at 66lb with around a 29.5 in draw length. Easton A/C/C 3-60/340 weighing in at 423 grains. String loop. 2 tie on knocks and a true-peep. I am getting 277 fps. Shoot this for both hunting and 3-D . Both limbs bottomed out and the strings and cables are adjusted for my exact draw length. It ain't in the speed. It is in the yardage estimation and shootability.
