Roskoe,
My younger sister shoots a Hoyt set at 52 lbs. She tips her 2013s w/ 75 grain Rocket Mini-blasters. To date, she has bow hunted elk for ten seasons. She has killed 4 bulls and 3 cows . It would be a tough sell to convince her that mechanicals have little effect on elk. I'd be willing to bet she tells you to risk it!
