I' d have to say if your draw length is over 27 inches, your 5575' s are too light. Go with at least the next heavier shaft for broadheads. My Pat Dually is shooting unbelievable at 66 pounds, 29 inch draw, CX 400 hunters with a Muzzy 4 blade 100 grain. Arrows weigh 457 grains and are doing 273 fps for 75.65 foot pounds of K.E. I noted that the best tune has the left side of the string {right handed bow} aligned with the point of the arrow and the left side of the riser and about 5/16" nock high. I also slid the V-blocks down to the riser, good luck
