I have a 03' Pat.. set at 50 lbs.

With my old alpine, it was set at 56 pounds and i drew it with ease. At 50 lbs, Its extremely hard to pull back the bowtech. Is it because of the infinity cam? Is it really harder to draw back than a true 50 # bow?

just wondering cause league tomorrow is gunna rape my arm.... that is if i can get through my 45 shots
