If it feels like 50lbs it probably is 50lbs!
Am I the only one who draws a 70lb bow (no matter which brand) and it feels like a 70lb pull? 70lbs is 70lbs no matter how you cut it. Somewhere in the draw cycle it's going to hit 70lbs and it's going to feel like 70lbs.
It all depends on how long it stays at 70#. A very smooth bow will peak at 70 very quickly. If you are used to drawing a bow at 70 that is not smooth, a smooth bow will put a much less strain on your arm although each are 70#. Hold your arm out empty and see just how fast it becomes heavy. Same principle.
