My older bow a High Country with twin hatchet cam and 100 lb limbs was shooting 283 at 80 lbs. Made it hard for some of those longer hold times. I switched to a High Country Carbon 4 runner extreme single cam this year and pulling 70 lbs I' m shooting at 310 with the same exact arrow.

Because the bow is quieter, easier to hold, more user friendly when tuning the upgraded bow was a blessing. I agree with these guy' s if your comfortable with the bow and can shoot consitantly accurate why change. However if the bow is un-comfortable like in my situation change but maybe wait for next year so you can adjust to the new bow.
